Interesting video. But it must be stated that Lawler is drafting the younger paddler, so he’s putting out less power to stay at that speed. Potentially 10% to 20% less. Also, he could be applying greater power for each stroke. But more than likely, he’s also a more efficient paddler due to years of training. Having said that, it’s useful to study the current multiple-distance world K1 paddling champion, Fernando Pimenta from Portugal. Even at that very highest, most elite level of racing, he has a slower cadence for a given speed EVEN when he’s (normally) leading a pack. Then he just pulls away and wins, still maintaining his phenomenal form and power at a lower cadence. I just (age 66) started paddling seriously a month ago. I find myself paddling at low stroke rates (around 50) so I can better control my movements and attempt to feel the water better. Maybe that’s a good thing. But I do consider myself a CCRAP student, my technique mostly being, well, crap, leaving a lot of room for improvement! I currently average about 4.5 mph (4 knots per hour) and am concentrating on 5 mph as an intermediate goal. Appreciate this site!

A feature of Ivan's stroke has always been the full extension of the arm into the catch and through the power phase. The young paddler, by crooking his elbow a little at the catch, shortens the forward length of the stroke and applies a greater proportion of his power to the back part of the stroke where the blade is starting to pull water upwards (wrong direction of vector and sinks the stern).
