Yo-Yo IR1 level 3
At level 3 of the Yo-Yo IR1, the required speed is 13 km/h: 2 runs of 21.08 s each. The level lasts 42 s; when it ends you have covered 160 m in 1 min 29 s. Completing it in full credits you with a MAS of 13 km/h, roughly 40 ml/min/kg of VO₂max.
We are still in the lower part of the scale. At this speed most healthy adults run comfortably; the point is to stay exactly on the beep, without getting ahead, so you do not pay later for energy spent here.
The previous level, 2, was run at 12 km/h. The next one, 4, moves to 13.5 km/h and counts 3 runs instead of 2. 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.

Frequently asked questions
What MAS does level 3 of the Yo-Yo IR1 give?
A MAS of 13 km/h, provided you complete the level. If you stop midway, the scoring rule credits the last full level, so 12 km/h (level 2).
How long does level 3 last?
