My idea is to leverage Strava's data hub collection since so many apps, and devices center around Strava for posting all major key metrics for runners. As a prediction analysis, it can be setup with a disclaimer that it is just a prediction so outcomes may vary but, with all this data, it would be great to view if you're on track to hitting your next race's target.
Say you are training for a marathon, based on aggregated data analysis of all runners on the platform, are you on track to hit your numbers? are you training too little, or are you training too hard (too high of intensity hr) are you risking injury for not taking any rest days based on historical information of all runners?
