Yo-Yo IR1 level 13
At level 13 of the Yo-Yo IR1, the required speed is 18 km/h: 8 runs of 18 s each. The level lasts 2 min 24 s; when it ends you have covered 3 000 m in 24 min 02 s. Completing it in full credits you with a MAS of 18 km/h, roughly 59 ml/min/kg of VO₂max.
We are at the top of the table, the territory of well-trained athletes and endurance specialists. Few candidates in any entry test get this far, and no official standard requires it.
The previous level, 12, was run at 17.5 km/h. The next one, 14, moves to 18.5 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.
