It's much easier to motivate to keep running when you know that even if you stop you're going to have to hoof it the same distance home regardless. It also makes it easier to extend the run if you're feeling strong -- "I'm almost home, but I'll just turn left here and add a loop around the park."
No way in hell I'm going to run outside on a track on a Boston winter night, but I sure as hell am looking forward to in the summer!
Besides, I need the machine to tell me how many miles I've run so I can post in the 'SF runs around the world' thread with utmost accuracy
