Disregarding hills (since I walk all of them): 1. How strict are you about adhering to this? 2. Do you let terrain dictate at all, i.e., if you're on a nice, easy downhill and it's time to walk for a minute, do you go ahead and finish the hill then change to the walk? 3. Do you do all of your training runs with the 5/1? I'm going to be participating in my first 50k next month. I think instituting this will be a big help. Your thoughts are greatly appreciated.

Maybe I'll try this question over on kickrunners. Sherpagirl, I'll let you know what kind of answers I get.

Thanks

Good luck! The folks over at kickrunners are loaded with experience and wisdom. Many of them migrated there when Coolrunning fell apart.
