Hi, I guess this is on the todo list already concerning “running” in general. It would be great if we could choose Speed, Pace or even gradient adjusted pace in the Fitness and Compare Tabs. I am thinking about HR vs. Pace; Power vs. Speed and so on.
There is a lot of running stuff on the todo list and I have just added these. For GAP I will have to develop/find a model as Strava doesn’t give that out via its API.
This could be worth a read - the Gravity Ordered Velocity Stress Score (GOVSS) model.
If I recall correctly from a previous read it can be used to determine GAP, or even calculate a power metric (excluding atmospheric variables of course) if have athlete data like weight.
