Exactly. By comparing your performance to others it also encourages addiction always activity and keeps your spirit up. You should check out how it integrates with Runkeeper and other fitness apps, since I know you are a fan of walking. FUCK AUTOCORRECT
I do a fair old amount of running (eg last month I did 220+kms), I have been using Runkeeper for a couple years now and find it pretty good at base tracking. It is reasonably consistent with the GPS although it does glitch in heavy cloud the odd time or if you are in dense forest etc. I like how you can designate routes etc and then try to beat your best times. You can add notes etc post exercise and program specific runs. Its good for reviewing elevations etc.
