At best, this can temporarily slow even the most accomplished and experienced runners, but it can also render a runner unable to muster much more than a walking pace for the remainder of the race and may prevent some from finishing. In the marathon, terms such as “hitting the wall” (HTW), “bonking”, or “blowing up” refer to the sudden onset of debilitating fatigue that can occur late in the race. We also find the finish-time costs of hitting the wall (lost minutes) to increase with ability r 2(7) = 0.91, p < 0.01 r 2(7) = 0.81, p < 0.01 for male and female runners, respectively.
Although, notably the effect size of these differences is small. And male runners slow over longer distances than female runners: 10.7km vs. 0.37 is noted, for male and female runners, when comparing their pace when they hit the wall to their earlier race (5km-20km) pace, with t(475, 199) = 60.19, p < 0.01, d = 0.15. When runners hit the wall, males slow more than females: a relative slowdown of 0.40 vs. Such slowdowns are more frequent in the 3 years immediately before and after a recent personal-best (PB) time for example, 36% of all runners hit the wall in the 3 years before a recent PB compared with just 23% in earlier years, χ 2(1, N = 509, 444) = 8, 120.74, p < 0.01, OR = 1.31. We find male runners more likely to slow significantly (hit the wall) than female runners 28% of male runners hit the wall compared with 17% of female runners, χ 2(1, N = 1, 928, 813) = 27, 693.35, p < 0.01, OR = 1.43.
