So, with my training for my 5 Miler next month, I'd been running outside at about 7AM. If I haven't managed to do it outside, I'd just bring it onto the treadmill. I'm wondering what other people's experiences are in doing their training for road races inside. Has it helped or hindered your progress? I'm thinking it can only help, simply because I then get the distance logged, and I don't pass out from heat exhaustion, I tend to dehydrate pretty easily.
