Despite the prominence and growth of ultra-trail running events in recent years, there remains limited research investigating the physiological effects of such extreme distances and the intricate relationship between sleep and recovery in ultra-marathoners. New research from the Ultra-Trail du Mont-Blanc (UTMB) unfolds new details of sleep and recovery. A recent study published in the Journal of Science in Sport and Exercise, titled "Sleep and Subjective Recovery in Amateur Trail Runners After the Ultra-Trail du Mont-Blanc (UTMB)," aimed to investigate sleep parameters and recovery in amateur trail runners following the UTMB.
