Here's where to start.
I'm Ric Stern — I created the MAP ramp test protocol used by Zwift, Rouvy and MyWhoosh. I've been coaching cyclists for nearly 30 years. Here's the fastest way to get something useful.
If you came here from Reddit — welcome. Everything on this page is free to use. The calculator below will give you your training zones, power profile, VO₂max estimate, and PSTS score based on your MAP test result.
If you want to go further — The Collective is group coaching built around the same methodology, and 1-to-1 coaching is available if you want something more personalised.
Start with the calculator. Everything else follows from there.

"Ric took me from a 5:58 finish at Dakota Five O in 2024 to a 4:45 finish and a podium in 2025. At 52 years old it's been fun reaching new heights in bike racing."
"I train under Ric for 3 years. I really improved a lot, got silver medal at Masters Nationals. I have never met Ric — I am from a different country and our training is only through the internet. But it does NOT matter. You can really be professionally trained this way. My results are proof."
