<bold>Purpose.</bold> The association between anthropometric and training characteristics on an athlete's performance has been investigated in swimmers, cyclists and runners, but not in inline skaters. The aim of this study was to investigate the relationship between anthropometry, pre race preparation and equipment in the finishers of the longest inline race in Europe, the ‘Inline One eleven’ over 111 km in Switzerland. <bold>Basic procedures.</bold> We investigated the association of anthropometry, training, and equipment variables with race times in 84 male ultra-endurance inline skaters using bi- and multivariate analysis. <bold>Main findings.</bold> In the multivariate analysis, percent body fat, duration per training unit, and personal best time in the ‘Inline One eleven’ was related to the race time for all finishers. Out of the 84 finishers, 58 had already finished an ‘Inline One eleven’ while 26 participated for the first time. Speed in training and the kind of skates worn were related to race times of the 26 inexperienced finishers. The inexperienced finishers skating with custom made skates were significantly faster with 229.1 (12.7) min compared to inexperienced finishers using ordinary skates finishing within 290.8 (35.4) min (p < 0.001). For experienced inliners, body mass, the sum of skin-folds and percent body fat correlated to race time. <bold>Conclusions.</bold> We assume that inexperienced athletes in ultra-endurance skating need time to gain the experience necessary in choosing the correct equipment and doing the training in order to successfully finish a long-distance inline race. Experienced inliners can only improve race performance in an ultra-endurance inline race such as the ‘Inline One eleven’ through a reduction of their body fat.
