Race time prediction
Strava is gather billions of data points for similar runners. When I'm gearing up for a race I pick a target and go for it, I'm a novice and I'm not sure if my targets for race time are correct.
What I would love is for Strava to analyse my profile and tell me what the mean, min, and max race times are for runners that do similar mileage and pace as I. This would be very valuable especially for longer distances such as marathons so I know what I should be aiming for and pace myself accordingly. You have the data to make these sort of recommendations.
