I'm game! I'm training for a 5k (and then later this year I'm going to start training for a half marathon) now, plus the random hiking I go on.
I keep track with RunKeeper. I love them so much! They have a free or paid app on the iPhone, and you can track running, walking, hiking, biking, swimming, all sorts of things all on the same app, and they have a separate website. You can have friends on there and follow each other to keep each other motivated. If anyone has one or wants to get one, let me know!
Actually, RunKeeper's goal tracking is only for one activity, so I can't say "Run + Hike 1000 miles" like I'd intended on, so mine is going to be only running. I run every other day, so I'm going to say 650 miles this year, because once I get started training my half marathon, I may decide I need to wait a while and keep working on my time for the 5k.
