Four male and five female skiers performed individual time-trials of 15 km (men) and 10 km (women) in the skating and classical techniques on two consecutive days. Races were performed on the same 5-km course. The course was mapped with GPS and a barometer to provide a valid course and elevation profile. Time, speed and heart rate were determined for uphill, flat and downhill terrains throughout the entire competition by wearing a GPS and a heart rate monitor. Time in uphill, flat and downhill terrain was ~55, 15-20 and 25-30% of the total race time for both techniques and genders. The average speed differences between skating and classical skiing were 9 and 11% for men and women respectively; and these values were 12 and 15% for uphill, 8 and 13% for flat (all P<0.05) and 2 and 1% for downhill terrain. The average speed for men...
