“…To our knowledge, this was the first study to report on musculoskeletal injury rates in ultra-endurance runners performing consecutive marathons on a repeat road-based course. In our study, 95.16% of runners sustained injuries, which is higher than reported in previous multi-day endurance running research (56.5-84.8% [10,[13][14][15]. This averaged at 4 injuries per runner, compared to 0.71-2.7 injuries per runner in previous studies [9,13].…”

This averaged at 4 injuries per runner, compared to 0.71-2.7 injuries per runner in previous studies [9,13]. The overall injury rate was 90.13 per 1000 hr, which again is higher than that observed by Krabak et al [13] in a five day off-road ultra-endurance study (65 per 1000 hr).…”

“…In a systematic review and meta-analysis into incidence of running related injuries per 1000 hours of running in different types of runners, only one study to date has recorded this [12]. Krabak et al [13] recorded an incidence rate of 65 injuries/illnesses per 1000 hours running, and 3.86 injuries per runner. However, this five day staged 240km event over desert/wilderness terrain was performed in several locations throughout the world and with a wide variance in location temperature (10°C-48°C) and altitude (-30-+4300 m).…”

“…Previous research has either investigated races on a repeated athletics grass track-based course [10], which lacks external validity, or road [9] and wilderness terrain [13] over a set point-to-point long distance, which lacks between day repeatability and reliability of terrain, direction and surface camber. To our knowledge, no study has evaluated injuries in multiday endurance runners performing a repeat course, over consecutive days.…”

Objective: To describe musculoskeletal injury rates in recreational runners completing ten marathons over ten consecutive days to help event organisers plan future injury preventative advice and strategies.Methods: An observational study involving 27 recreational runners (age 45.1 ± 7.47 yrs, mass 74.5 ± 12.39 kg, years running 11.6 ± 9.42 yrs, average weekly mileage 41.9 ± 12.72 miles). Main outcome measures included total and percentage of musculoskeletal injuries, timing of injury occurrence during 10-day event, and daily individual marathon times.Results: Twenty-six runners sustained 108 injuries, averaging 4 injuries per runner (90.13 per 1000hr). 89% of injuries involved the lower extremity; 24.1% foot, 18.5% hip/buttock, 16.7% ankle and 16.7% lower leg. Common injuries were blisters (15.7%), Achilles tendinitis (11.1%), medial tibial stress syndrome (MTSS) (10.2%), iliotibial band syndrome (ITBS) (9.3%) and low back pain (LBP) (9.3%). 64.3% of injuries were sustained to the left limb. Chi-squared analysis revealed more injuries in days 1-3 than days 4-6 (p=0.013) and days 7-10 (p=0.001). Repeated measures ANOVA comparing Days 1-3, 4-6 and 7-10 showed a significant main effect (p=0.039). Post hoc analysis revealed Days 1-3 were significantly quicker time than days 7-10 (p=0.037, difference of 0.276 hrs). Conclusion:Blisters, Achilles tendinitis, MTSS and ITBS are the most common lower extremity injurie in multiday marathons runners performing a repeat course over 10 consecutive days. Runners entering these events should perform appropriate injury prevention programmes. Runners should also be more reserved at the beginning of multiday events to avoid high initial injury risk. However, further investigation of injury rates and risk factors using larger sample sizes is required.

“…However, it is even possible to run across a continent without an injury [107]. Despite the extreme nature and harsh environments of multiday ultra-marathon races, the majority of injuries or illnesses are minor in nature [103,108]. For example, during a 219-km 5-day stage race, lower limb musculoskeletal injuries accounted for 22.2%, predominantly affecting the knee [109].…”
