I have developed an app that uses google health and a few other metrics to figure out how you would do in a race against an olympian. It uses runs that you have already completed to estimate if you could make it to the olympic podium. It will also let you run against your Facebook friends or twitter followers if they sign up to. It is free and you can check it out here:
