Figure 1. Schematic diagram of the mountain bike course (one of four identical laps). Each lap was divided in three sections: Section 1: uphill section (uphill; start at an elevation of 318m; length ~2095m; and ended at an elevation of 456m). Section 2: rather flat terrain (flat; length ~1553m, and ended at an elevation of 462m). Section 3: downhill section (downhill; start at an elevation of 462m; length ~ 2439m; and finished at the starting point).
