Yo-Yo IR1 level 8
At level 8 of the Yo-Yo IR1, the required speed is 15.5 km/h: 8 runs of 19.29 s each. The level lasts 2 min 34 s; when it ends you have covered 1 400 m in 11 min 42 s. Completing it in full credits you with a MAS of 15.5 km/h, roughly 49 ml/min/kg of VO₂max.
This is where entry tests are decided. At 15.5 km/h breathing becomes clearly audible and the turn starts to cost. The next levels are earned in training, not on the day.
The previous level, 7, was run at 15 km/h. The next one, 9, moves to 16 km/h. On this test the gap between two levels is small in speed and large in feel, because fatigue carries over from one level to the next.
