Since last year I use this software on my iPhone and the assosiated homepage to track all my sport activities. As you can see, the last couple of months I did approximately 150 kilometers of sport.
Does not matter, what. In the winter months I did a lot of cross country skiing and now, in summer, I restarted with biking, mountain biking and running.
The software is very nice. You can also enter activities, you did not track with the iPhone and it shows you statistics like the one you can see here.
