Thanks @hisnameisollie! I would be really happy to see this implemented and applied in practice. I know many people that collect this kind of data and measure the miles they run, count swim lenghts etc.. Some do it just for stats, some to measure/improve their performance and some to loose a bit of weight and most of those people would be inspired and encouraged to do even more if it is for a cause. It would be great to be able to use a custom app on a mobile phone or import the data from TomTom/Apple/Nike etc. watches or similar wearables. Fingers crossed!
