Navigating Adversity: Non-Completion and Evacuation of Trail Runners at the 2022 Magoebaskloof Forest Marathon

Background: Trail running occurs on natural, uneven terrain. The literature is limited in exploring factors that contribute to trail runners not completing a race. Objectives: This study firstly investigated self-reported reasons for runners who did not finish (DNF) the 2022 Magoebaskloof Forest Marathon across 10km, 20km, 34km, and 50km distances, and secondly assessed runners' evacuation methods. Methods: A descriptive cross-sectional study of consenting trail runners (n=429) who completed the post-race DNF survey (10km, 20km, 34km and 50km distances). Within two weeks post-race, runners reported whether they finished, reasons for discontinuing and evacuation methods. We report numbers (n) and point prevalence (%). Results: Of the 228 runners who completed the post-race survey, 16 (7%) DNF. DNF runners entered the 34 km (19%) and 50 km distance (81%) and were aged 31-50 years (94%). No DNFs occurred in the 10km and 20km races. Approximately 27% did not meet cut-off times, while 19% got lost despite trail directions. Other contributing factors included pre-existing and new injuries (23%), illnesses (15%), and inadequate training (8%). While 50% of the DNF group had >5 years total running experience, only 19% had >5 years of trail running experience. Runners who finished the trail race had significantly more trail running experience than those who DNF (p=0.0082). The primary evacuation method was hiking back to the nearest aid station (63%), with 19% subsequently transported by shuttle. Conclusion: Multiple factors may have contributed to the race non-completion. Many DNF runners started with injuries or illnesses, inadequate training, or limited trail-running experience. Event planners should improve measures to prevent runners from getting lost. These findings emphasise the importance of preparation, navigation skills, and race management in ensuring trail running safety and success.
