A VO2 max test performed outdoors with a VO2 Master device involves a ~10-15 minute warm-up ride to the location, including short high-power climbs, followed by two to three full hill repeats at escalating power.

“I do most of my V2 max testing out Outdoors now I use that V2 Master device which I I love it would I would so so I'm going to leave from my house I'm going to ride 10 to 15 minutes to the place where I do my Hill repeat so that's a warm-up in and of itself and by the way getting there there are a couple of short little climbs where I'll do like 30 seconds of you know relatively high power just to get up over a little pitch I will do two to three full runs of the hill at escalating power before I'm truly going to hit my Max um so I'll do like a four to five minute up at a you know like not like a p like maybe 85% of what my maximum power would be for that climb come down for the same amount of rest period go up again at maybe 90% of what my maximum power would be come back down and then maybe I would go and give it like that the third one would be out there so by the time i' I've done it I've really warmed up”
