and energy cost of running per unit distance (C) were determined on the treadmill in 36 male amateur runners (17 to 52 years) who had taken part in a marathon (42.195 km) or semi-marathon (21 km), their performance times varying from 149 to 226 and from 84 to 131 min, respectively.

was significantly (2p<0.001) greater in the marathon runners (60.6 vs 52.1 ml · kg−1 · min−1) whileC was the same in both groups (0.179±0.017, S.D., mlO2 · kg−1 · m−1 above resting), and independent of treadmill speed. It can be shown that the maximal theoretical speed in endurance running (vEND) is set by
