Just discovered an extension for google chrome a few days ago, It’s called “Strava Sauce”. In case you don’t know, it gives you a lot more information about your run/ride, such as GAP, VAM, Estimated Power (for run and cycling) and so ever.
I don’t know if you can the data of it on intervals, but just thought It would be nice let you know about this tool. Here’s a quick look at it:
We probably all know that one and it’s like Elevate. I actually supported Thomas Champagne too, but since I dropped Google (fork) browsers, I don’t use those plugins. They both are available for Firefox and Opera too, I believe…
I took a few screenshots from the video. Unfortunately Strava doesn’t expose GAP through their API so I will need to derive that myself at some point (browser plugins don’t need to use the API). Need to do more “best efforts” stuff for runners.
