Corvallis to Portland Row (CPR): Part 3

ROI
In the previous CPR post, I alluded to some of the "investment" that some of us have made in this 115-mile rowing event. I'm speaking of the training, of course, but also the time and energy ascertaining better ways to:
  • prepare oneself physiologically (train long distance all the time?)
  • rig a boat for a long-distance row
  • replenish nutrients and liquids
  • deal with banal aspects like relieving oneself. 

There is the investment in time of mapping the course, setting up the GPS points, attaching hardware to your boat like bottle cages and the GPS mount. There are many little things like scrounging up a spare skeg, duct tape, first-aid kits, spare gloves, sunscreen and various types of food (it's easy to suffer from food fatigue in a long event). There is the small matter of committing to memory many of the hazards mentioned in the previous post. So, for all this effort what does one get out of CPR?

With all due respect to Bill Byrd and Tiff Wood, the medals (see below) are not the reason why people train for and row Corvallis to Portland, despite what the CPR web site says. Below is my take on why I do it and how I train for it, not necessarily in that order.

Robert, Corinne and myself sporting our CPR doorstops medals.


Feel the Earth Move
Both my wife and I have been training for the 2011 CPR for some time. I've been training for this event pretty much since October 2009 and she's been training for at least the last 6 months. Of course, many years of rowing (and other sports) and competitions have preceded these particular efforts, so it's really a training continuum. If you think of a training log as a seismograph, then our CPR training would register as a sustained Richter rumble, but only barely distinguishable from the surrounding training noise.

Past Results Don't Guarantee Future Returns
Beth has completed CPR twice, once in a double (2007) and another time in a quad (2008). I rowed in the 2007 CPR, but lasted only 85 miles as wrist pain and swelling prevented me from being able to feather my oars effectively. I'm better prepared this time around and my body seems to endure the stresses better.

How Do You Train For a 115 Mile Row?
The answer to that is not clear.  Many of my training queues come from my ultra-running friends:
  • Frequent: 4-6 times a week, but also lots of rest days
  • Continuous: there is no off-season
  • Long distance: up to 45km at a time, with frequent 25-35km efforts and seldom less than 20km.
I briefly did some shorter, harder efforts (4 x 1200 meter intervals) prior to the Covered Bridge Regatta. I also briefly did some 2 x 20 minute intervals prior to the Open Ocean Regatta. There is some research to suggest that these more intense efforts might boost mitochondrial- and capillary density, both of which might help in a long-distance row. Still, 95+% of my training has been of the slow, steady variety. I average about 2:30/500m and just plug along. Lately, I have been rowing a little faster pace and that might be fitness or it might be smoother water. Sometimes I speed up to chase down a friend, just so I can have someone to talk to.

I have made sure to experience two consecutive days of longish training bouts so I can see what I will feel like on the second day. So, I might row for 4 hours one-day and 2 the next. I have had no problems with these efforts. No back pain, no wrist swelling, no knee discomfort and only a mildly sore posterior. Often I get off the water, feeling like I could keep on rowing. That's a good thing, since those rows are a small fraction of what I would have to row in the first day of CPR.

I consider eating, drinking and resting as part of the whole training scheme. I try to make sure that I eat a fair amount during my longer workouts, if for no other reason than to get used to it when I row in CPR. I also try to consume lots of carbs immediately after my longer workouts, per information I learned in writing this post. Still, I have been losing weight and I didn't have a lot of weight to lose. Yes, I'm eating a lot of protein too, but I may not be getting enough fat(?).


How Do You Rig For a 115-Mile Row?
I've spent an inordinate amount of time contemplating this and futzing with my foot stretcher height and angle, my catch angle, inboard and outboard oar length, my stroke rate, my upper-body position etc.

I consulted various folks and the following, among others, responded: Rob Slocum, Valery Kleshnev, Stephen Seiler, William Atkinson, and Carl Douglas. I was surprised by many of their answers:

Person Rigging Advice Stroke rate advice Quotes
Rob Slocum Would probably go lighter than when he previously rowed CPR 20-23 "I put vaseline on my hands and then put the batting gloves over them. No blisters. Redo the vaseline at each stop. I did a mileage binge for forty days or so leading up to CPR. Like 1000k on erg/water, something like that. Wow. It boggles my mind to think of it."
 Valerie Kleshev "longer catch angles" "I’ve never measured or studied marathon rowing. If someone would be able to give complete advice in this case, many coaches would lose their jobs." (!)
William Atkinson higher gearing
"maximize catch bow angle"
"Increase the outboard.
By all means use a big blade."
low stroke rates "strong pull/low rating vs. lighter pull/higher rating" (!!)
Stephen Seiler "I really dont think the gearing (oar outboard length) will make that much difference. Your own stroke rate choices are more important by far. So, I probably didn't tell you anything revolutionary, but my vote is for a relatively low rate." "My philosphy is that when rowing with the wind or with the current, you use lower stroke rates and let the extra run of the boat work for you. I also think that rowing at a lower rate will actually protect your back because it will add up to hundreds of saved strokes over the course of the many hours of rowing in front of you." "In long races like this, you have to use the wind and stream to your advantage and search for the best conditions on the river all along the way. Also, dont be fooled into rowing too hard in the first hour or two. Whatever gains you might make then will be lost many times over between hours 3 and 10."
Carl Douglas "A slight shortening of the stroke can be as, or more effective than, changing oar gearing, since what you clip off the ends of the stroke will be just those parts which are most severely geared. You don't need more than a smidgen of shortening to significantly ease your effective gearing." "I agree completely ... about easy gearing & maintaining the rate - just spin it along." "Sustainable steady-state force application falls exponentially with planned distance. Power output also reduces, but you can maximise the work you usefully do if you re-shape your technique & loadings to increase pulling time (= time in the water). This will come if you keep the load light but waste no time between strokes - do not treat the recovery as personal recovery time.
Final thought - be comfortable. Check you are comfortable with your equipment over longish training distances & make all changes necessary to achieve comfort since bits of you will have all sorts of problems if how you sit or what you do causes them local pain that's not directly related to boat moving."

After experimentation, I found myself agreeing with Carl Douglas on virtually every account.

For sprint racing, e.g., the Covered Bridge Regatta, I set myself up further into stern relative to the pins, so that my catch angle was fairly steep. I set the shoes relatively high and the shoe angle relatively steep. I found this arrangement unsustainable for longer rows (20+ km), day after day. My ribs, shoulders and lats didn't agree with this set-up. Even my abs complained.

For distance rowing, I "relaxed" the settings on everything: I lowered shoes, lowered the foot stretcher angle, reduced the catch angle by moving the foot stretchers toward the bow a few notches. My oar length--285 cm--actually increased 1 cm from 284. I've been rowing relatively upright, with almost no forward lean (from the hips) at the catch and almost no layback at the finish. The why of all this is a potentially long discussion, but it all seems to result in reduced perceived load and I can sustain a stroke rate between 22 and 25 with little threat of feeling over-geared. I'm sure I am sacrificing some stroke length, catch angle, and optimal power application for sustained comfort, but that seems like a prudent goal for an event that might take 12-13 hours.

I briefly had some wrist discomfort, but that seemed to go away after rowing less rough water and frequent icing and vitamin I (-buprofen).

The only thing that has bothered me much at all through this training is a recent coccyx (tailbone) discomfort. This may be related to my weight loss. I seem to have an increasingly bony ass. I'm now experimenting with a seat pad.

Why?
I think it was Napoleon Bonaparte who said "It is only one step from the sublime to the ridiculous." That may apply here. What I find, though, is that the more I prepare, the closer I stay to the sublime. To not prepare, on the other hand, would lead to the ridiculous.

Are we freaking done yet?

The longer the training, the more I seem to enjoy it. Often, it takes 5 or 10 k just to get comfortable, but then I get into a nice groove. The rhythm of long rows leads to an almost mindless state, a type of mental floss if you will, cleaning out the cerebral plaque of everyday living. Stroke after stroke, meter after meter, kilometer after kilometer. When I start rowing, I usually contemplate the day's non-rowing goals--things I want to get done--but after a few "klicks" I stop thinking too much and I get into a pleasant state of conscious semi-trance: I'm alert, but not trying to volitionally process anything. It's as if the meta-awareness part of me is turned off and only the animal part of me is left. My mind becomes like my heart and lungs, functioning autonomically. I'm aware of where I am and what I am doing and not a whole lot else. This is when the miles fly by and nothing much happens: sometimes, the mundane is the sublime.

Not that my rowing surroundings are boring, mind you. On a typical training day I see bald eagles, great blue herons, osprey, geese and their goslings, and fish jumping out of the water. I see coyotes, foxes, llamas, horses and cows on the lake shore. I have seen deer swimming across the lake, not that deer are rare around here, but seeing them paddling is a bit unusual.

Occasionally I'll see a tandem duo of bald eagles dive-bombing ducks. This is wildly entertaining if slightly gruesome.

Every once in awhile fighter jets from a nearby airbase will come screaming seemingly just above the water in some kind of Top-Gun chase scene. That puts the adrenaline in overdrive.

Local firefighter helicopters train for future fires by sucking water out of Emigrant Lake and then dumping it again. Imagine a huge insect with a gigantic proboscis dipping into the water and then letting it loose a few minutes later.

I've seen seaplanes land and take-off and jetboats send up 30-foot high plumes of water.

Occasionally I will see other rowers narrowly missing each other, but I'm more worried about the fishermen trolling with their eyes on the screens of their Bass-o-matic fish finders. Colliding with a fishing boat can harsh your mellow.

What does my local rowing experience have to do with CPR? Well, I had better enjoy the local rowing because I'm going to do a lot of it. The time I spend rowing each week might be the same amount of time I spend rowing at CPR. Add up all the training weeks and hours and you realize that the actual event time is a small fraction of the training time.

I train because I enjoy it. I'm not doing it for the fitness and only secondarily for the racing. The race is certainly a big part of this endeavor and more than just icing on the cake. I have to remind myself that the race is not the whole goal, though when the race seems likely to be nixed, this is hard to stomach. Still there is intrinsic value to the training itself. The race may be the big goal but it helps sustain the training which is the other goal.

I will be depressed if this year's CPR regatta is canceled. It would be like training for the Western States 100-miler the year California fires prevented it from happening. Except in my case it will be like missing two consecutive Western States: last year's CPR was scratched and this one appears likely to be. And, while there is only one Western States, there are plenty of other ultra-marathons. There is no other fresh water distance race like CPR anywhere in this country and maybe not anywhere.

Corvallis to Portland Row (CPR): part 2

Navigating Backwards
The previous CPR post mentioned some of the hazards one might encounter on the Willamette river between Corvallis and Portland, including docks, rocks, and locks. 

CPR rowers face a number of potential hazards

Some of these are well-known and documented by the Oregon State Marine Board here. Race organizers also issue a list of hazards by river mile. 

The Willamette Falls Locks: It's not a good idea to be next to the sides when they let the water out.

The Google map below lists many of the hazards and indicates aid stops and other "features." Of course, hazards like moving craft and wakes can't be mapped.

GPS: We're the Fagawi (Again)
A mounted GPS comes in handy for traveling backwards. For the 2007 CPR, I mapped the route in Google Earth and then derived the GPS coordinates for all the various hazards along the route. As we rowed,  the hazzard markers appeared on the GPS screen just before we reached the hazzards on the river. I used green markers to indicate that we should row to starboard and red markers to indicate when we should row to port. This can get confusing, but after awhile we got used to it. Being rafters and kayakers, my doubles partner and I would lapse into "river right" and "river left" directions occasionally.


Objects in Mirror Are Closer Than They Appear
A hat-mounted rear-view mirror comes in handy too. Fashion statement aside, these mirrors are really helpful. They, too, take awhile to get used to and they are no substitute for looking around. I imagine I looked like Stevie Wonder, rocking my head side to side to capture the full view of things.

I used both a mirror and a GPS in the 2007 CPR, while rowing in a double. We managed to avoid hitting anything. Just in case, though, we carried some duct tape and a spare skeg for the boat and a small first-aid kit for us.

Rowing With the Flow
Rowing with a current is a different experience. My friend Robert and I rowed on the Willamette in January last year (2010) when the current was quite strong. Just launching off the dock was a bit daunting. Rowing first upstream we battled the current and found eddies and protected areas. Then turning around we found ourselves just zipping right along. On the first weekend after Memorial Day (when CPR is scheduled), the flow is not usually that substantial, but there is considerable variability.

In 2007, the flow registered 3 feet on the scale (see bottom), and while the current was a few knots per hour, by the time we reached mile 60, there was almost no current to speak of. Last year (2010), the river rose to near flood levels, the flow approached "flood action stage" and CPR XII was canceled.

This year, the flow is already too high and the projected levels don't offer much solace. The CPR website stipulates a flow between 2 and 6 feet on the gauge. The flow is currently over 15' and projected to rise to nearly 17' (over 20,000 cubic feet per second (cfs)). Around race time (June 4 and 5), the flow looks to be around 15,000 cfs. This would make for an expeditious trip down the river!

Willamette current flow and projected.

The Willamette river snow water content is ~200% of normal for this date and as soon as it rains or warms up significantly, the river is likely to approach the "action" or flooding stage. The Columbia river, in which the Willamette flows, has been at the flood warning stage for several days already.


The snow melt, rain and river flow projections don't bode well for those of us who have a lot invested in the CPR event. More on that in the next post.

Corvallis to Portland Row (CPR): part 1

Length Does Matter
The 185 km (115-mile) Corvallis-to-Portland Row (CPR) is one of the longest rowing events in the world involving conventional racing shells. The Ringvaart Regatta (whose slogan is in English: Length Does Matter) at 100 km seems to be the next longest. Meanwhile, The Guinness Book of World Records suggests that the longest rowing event is the Tour du Léman à L’Aviron, however this regatta is "designed for four rowers and a coxswain in larger boats called 'yolettes.' " Meanwhile the Murray Marathon is longer still at 404 km, but it seems to involve primarily kayaks, canoes and surfskis over 5 days. The Atlantic Rowing Race, involving specialized craft, is clearly longer still.

Event Total Distance Longest One-Day Distance # Days Boat Types
Murray Marathon 404 km 96 km 5 Kayaks, canoes, surfskis. It's not clear that rowing shells are allowed.
CPR 185 km 137 km 2 Racing shells: 1x, 2x, 4x, 4+, 8+
Tour du Léman à L’Aviron 160 km 160 km 1 4+, 4x "Yolettes" generally
Ringvaart Regatta 100 km 100 km 1 Racing shells: 1x, 2x, 4x, 4+, 8+

 
Whether it's the longest conventional racing shell regatta or not, CPR is certainly the most understated. There are no brochures like Ringvaarts, no reports like the Murray Marathon's, and no fancy website like any of the other events. There is virtually no publicity, no marketing, and no self-trumpeting. Last year, the simple event website didn't even have a link to an entry form until right before the event was supposed to happen. Organized by Tiff Wood, better known for helping start the Crash-Bs (aka the World Indoor Rowing Championships), the bulk of the information about the event is basically contained in this one short paragraph.

"The distance is 115 miles, including a trip through the Willamette Falls Locks at mile 104. CPR is a 2-day event, with 85 miles rowed on the first day, ending at Champoeg Park with a campfire and an excellent catered dinner (bring your own tent). Then early to rise Sunday morning for the 19-mile row to the Locks, a half-hour to rest while descending 45 feet to the lower Willamette, then a mere 11-mile sprint to the finish. The medals, designed and made by Bill Byrd, are worth rowing the distance."

Nulli Complorantor
Don't let the phrase "excellent catered dinner" deceive you into imagining this is some cushy tour with brie and Sauvignon Blanc. Far from it, this is really a self-sufficient event with minimal support. Any food, drink, medical attention you need during the rowing portion has to come from you or your crew (if you have anyone). You will likely row for hours at a time without seeing a "race official".

This is not a closed course and there are many obstacles, including barely submerged tree stumps, rocks, logs, old dam walls, projecting docks, and an assortment of motorized watercraft like jet-skiers and wakeboard boats. Many past participants have run aground, ripped holes in the their hulls, knocked off skegs and generally abused themselves and their boats. Here is a paragraph from one of Ted Katauskas' accounts:

"We drifted alongside the other eight, which had also struck the log. Foundering, we paddled to a beach, removed our oars, and lifted our boat from the water. It was missing its skeg and had sustained an arm's-length gash in its bow; the other boat, beached nearby, had a hole near its mangled rudder. There was nothing to do but bake in the noontime sun. Our neighboring castaways from Corvallis cranked the volume on their cox box and converted their useless Dirigo into a karoake machine."

Lest you need more pampering or think you've earned the right to complain about your blisters, swollen wrists, butt aches, chafing, wind, temperature, wake from jetskis and wakeboarders, etc, think again. No Whiners is the motto for this event. 





Don't expect informative communications from Tiff either. He is laconic, borderline cryptic, and non-promotional. Once in a blue moon he will respond to email. It would seem he is more interested in rowing the event than organizing it. And, in fact, you may see him participate in a boat on one leg of the event or maybe the whole distance. 

Volunteers are sometimes obtained the day before from rowers' support crew. Susan Parkman seems to be heavily involved and one wonders if the event would happen without her.

Why do I care? I hope to row in CPR this year, actually in less than two weeks. More about that in the next post.

As Seen in Real Life #4: CPR Locks

Charlie Foxtrot

This shot was taken in 2007 during the second day of the 115-mile Corvallis to Portland Row (CPR) at the Willamette Falls locks. The next year, the locks were closed. Last year, there was too much water in the Willamette, so CPR was canceled.

This is actually a small fraction of the number of boats in this particular chamber of the locks at that moment. To fit, boats had to arrange themselves creatively. Most of these folks had rowed roughly 105 miles so for some the break at the locks was a welcome respite, while for others it simply delayed the finish (and getting off their seats). As is possibly evident in the photo, patience and camaraderie were in abundance.

It turns out that the Willamette Falls Locks are "the oldest continually operating multi-chambered canal and navigation lock system in the United States." This is according to a historical web site that is urging people to participate in a Lock Fest on June 18th of this year (2011). You can be part of a flotilla to descend through the locks. Funding for the operation of the locks is a perennial challenge, so this opportunity may not exist much longer.
