Even pacing wins time trials and loses championship finals

The physiology textbook says distribute effort evenly, and every slow metric final says the textbook is not the one running the race.

Even pacing is optimal. It is one of the few things in endurance physiology that is close to settled, and it is also close to useless in a championship final.

The reason is that a final is not a test against the clock. It is a test against eleven other people, and the prize function is discontinuous. Fourth is nothing. Third is a medal, a contract renewal, funding for a training group, a life. If you run the physiologically perfect race and finish fourth by a stride, you have optimised the wrong quantity with impressive rigour.

Watch how a slow tactical fifteen hundred actually resolves. Nobody wants the front, because leading costs you the ability to respond and gives everyone else a target they can see. So the field crawls, the first eight hundred goes by in something a decent club runner could manage, and then the race becomes a two lap sprint contested by people who have spent two years training their aerobic ceiling. The winner is very often the athlete with the best raw speed rather than the best endurance, which is close to the opposite of what the event is supposed to select for.

I think that is a design fault, not a tactical curiosity. If your event is decided by the last two hundred metres in every major final, you are running a heavily disguised eight hundred.

There are fixes and they are all unpopular. Pace lights on the rail for finals, which purists hate. Rabbits, which turn a championship into a meeting. Or semi finals structured to be run fast enough that only genuine endurance survives into the final, which is the least intrusive of the three and the one I would take.

None of that changes what an athlete should do next Tuesday. If you are in a slow final, sitting on the shoulder and trusting your finish is correct, even though the coaching literature has a hundred papers saying you are leaving time on the table. Time is not the currency being spent.

The one place the textbook wins outright is the individual pursuit, the rowing trial, the flat marathon with a functional pack. No opponent to answer, no surge to cover. There, go even, and go even to the point of stubbornness.

Everywhere else, the physiologically optimal race is a very well argued way of finishing fourth.
