Purpose: To give insights in the exercise profile during an uphill handcycling time trial in elite and recreational athletes. Methods: One elite and 13 recreational athletes with a lower limb disability performed a handcycling mountain time trial, the HandbikeBattle (HBB), of 20.2 km with an inclination of 863 m. Power output (PO) was measured during the race. For the elite athlete additional breath-‐to-‐breath oxygen uptake (VO2) was measured. In the month prior to the race values for the peak PO and the second ventilatory threshold (VT2) were determined during a graded exercise test. Next, 7 power zones were calculated. In addition, for the elite athlete the peak VO2 was determined. Results: Recreational athletes finished the race on average after 2 hours and 29 minutes with an average PO of 108 W (61% POpeak), cycling mainly in power zone 4. The elite athlete finished the race within 80 minutes with an average PO of 203 W (62% POpeak), cycling mainly in power zone 3. The elite athlete cycled during the first part of the race at an average Respiratory Exchange Ratio of 0.9, VO2 of 3.4 L/min (71% VO2peak), energy expenditure of 1190 W and mechanical efficiency of 18 %. Conclusions: The HBB is an intense race with a PO around or above the VT2, power zone 4 and higher, for a large amount of time for recreational athletes. Training for longer amounts of time at a PO around and above the VT2 is recommended in the preparation for uphill handcycling time trial.
