think about the training of a sprint oriented 400m runner. now think about the training of an 800m runner even on the speed side. there are huge missing gaps there. racing in an 800, and training for that race so that you can meet the potential of your 400m speed are two TOTALLY different things.
shoot, think about the training from a 1/2 marathon to racing a marathon. even that is a crapshoot on race day.
i applaud the gentleman for making an attempt at 800m regardless of the result.
i think there is a certain rabbit in oregon who can attest to the demands of moving from the 4 to the 8 and doing it well
