I was on the 12:30 (european time) session of the Zwift - ZA Tri Bike WO #2 - Aerobic Threshold Development .
All the intervals are divided by 10. For exemple, we had to maintain 245W for 12s instead of 120s. The total session is consecuently 7min instead of 70min.
Please correct the next sessions as they are programmed in the same way.
