Maximal O2consumption (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) whileCwas the same in both groups (0.179±0.017, S.D., mlO2· kg−1· m−1above resting), and independent of treadmill speed. It can be shown that the maximal theoretical speed in endurance running (vEND) is set by, its maximal sustainable fraction (F), andC, as described by:vEND=F··C−1. SinceFwas estimated from the individual time of performance,vEND could be calculated. The average speed of performance (vMIG) andvEND (m · s−1) were found to be linearly correlated:vMIG=1.12+0.64vEND (r2=0.72;n=36). The variability ofvMIG explained byvEND, as measured byr2, is greater than that calculated from any one regression betweenvMIG and(r2=0.51),F·(r2=0.58), or·C−1(r2=0.63). The mean ratio of observed (vMIG) to theoretical (vEND) speeds amounted to 0.947±0.076 and increased to 0.978±0.079 (±S.D.;n=36) when the effects of air resistance were taken into account. It is concluded thatvEND=F··C−1is a satisfactory quantitative description of the energetics of endurance running.
