And a few simply desire holding issues the best way they’ve at all times been.

Age groupings are supplied by most endurance occasions, but analysis suggests physique weight additionally must be thought-about as a significant predictor of operating efficiency in marathons.

Nonetheless, the analysis suggests weight performs a giant position in operating efficiency and dividing races by weight may assist extra folks benefit from the sport.
It isn’t an ideal answer, however it’s one thing price interested by if we wish to make marathons extra welcoming for everybody.
