I like Runkeeper. Start it when you put in and stop it when you take out. It will record your distance, speed, and track. It gives you a graph of speed over distance, and you can compare it to the map and your memory of wind and current conditions. When you are finished, you save your trip. It will display your track on a map. It uploads your trip data to Runkeeper's internet site, and you can share the link with others. It builds a whole library with all your trips.
I think it is a cool app.
