Rowing's suicidal opening five hundred is actually the right call

Every physiologist who watches a two thousand metre final winces at the start, and the crews going fastest keep doing it anyway.

A two thousand metre race is roughly six minutes long and crews spend the first fifty seconds of it doing something that looks like self harm. Rating forty five. Splits four or five seconds a five hundred quicker than they can possibly hold. Then the long, ugly, grinding middle where everything hurts and the boat feels like it is towing an anchor.

Ask a physiologist and you will be told this is inefficient, which it is. Even distribution of effort minimises the metabolic cost of a fixed distance. Anyone who tells you otherwise is arguing with arithmetic.

And yet the fast crews all do it, and have done it for decades across every boat class and both sexes, which should make you suspicious of the arithmetic rather than the rowers.

Two mechanisms make the fly and die defensible. The first is hydrodynamic and specific to boats. Drag rises with something close to the square of velocity, so speed is expensive to buy and cheap to keep, and a boat brought up to pace early then held there is doing less total work than one that has to be accelerated repeatedly by mid race pushes. Getting to hull speed fast is an investment, not a waste.

The second is oxygen kinetics. Your aerobic system does not switch on at the horn, it takes something like ninety seconds to reach full contribution, and the deficit accumulated at the start has to be paid whatever you do. A hard opening spends anaerobic capacity you were going to lose the use of anyway, and it does so at the moment when the aerobic machinery is being pulled up fastest behind it.

Then there is the part that is not physiology at all. Rowing is raced in lanes, side by side, with a crew that can see whether it is up or down. A length of open water at seven hundred metres is worth real time later, because the boat behind is now racing water while your crew is racing a plan. I would not want to be the coach who told a bow four to be patient and then explained the video afterwards.

Where I would push back is the third five hundred. Crews accept the slump as a law of nature and it is really a consequence of how badly they rated the first one. Attack the start. Then defend the third quarter like it is the finish, because that is where the medals are actually lost.
