...and mine is that in an average tri ride, you are going to be losing speed, then bringing your wheel back up to speed a number of times. The causes can be terrain, wind, traffic, or even rest stops. Bike riding is not an idealized wheel in a physics equation. You have proposed a steady state equation, where there are, in reality, many variables intruding on your argument. This is exactly what true believers do. They simplify arguments, possibly because it makes them feel better about themselves. I honestly do not know or care. Just stop already.
