>Cross Training>Push ups and back pain
Roads were made for journeys...
2013 Goal: Make 3:00:16 go away.
As people always say with running, just do less of them.
It sounds like your lower back is the weak link, so do half or a third of the amount of core work you were doing, and build up.
It works with any physical conditioning workouts, not just running. I was talking to a guy I know who does powerlifting a few years ago and was amazed at how similar the training periodization cycles were.
Long Drawfs Fast
Run until the trail runs out.
Alternately, you could do knee push-ups, which although easier on the arms are also easier on the back.
Best Present Ever
