Neutral Predisposition

For the well rounded runner who races all different distances and fares similarly against their peers at most distances from 5k through the marathon. If in doubt which chart to use, use this one as the majority of runners will fall into this category.

Long Distance Predisposition

For the aerobic monsters who tend to do better than their peers in the longer races (half marathon and marathon) and focus their training and racing there.

Short Distance Predisposition

For the speed demons who tend to do better than their peers in the shorter races (5k and 10k) and focus their training and racing there.
