Xperiathon - a solo marathon

For all you active smartphone users… Xperiathon is the world’s first marathon that takes place all over the place. A regular full or half marathon in all aspects except one, you run wherever you choose and you do it alone.
The race is open to everyone with Endomondo, MapMyFitness or RunKeeper installed on their smart-phone. When you have covered the distance (half or full marathon) you end your run and tap save. This will send your run data to your run tracking service and they will get it from there.
