Demonstrates the law of diminishing returns as the gap between lines closes over time and the improvement in fatigue resistance as the line slope flattens. Further low intensity base training is unlikely to yield an improvement in speed but perhaps could squeeze out a bit more fatigue resistance. Time perhaps to use the base as a springboard for something else! - Or extend it further into the abyss that is ultra running.

Crap, that's impressive! Time to move to the next phase of training.
ReplyDeleteGreat graph Grellan. Easy for even an uneducated bloke like myself to understand ;)
