I'm choosing to run and train through the back and leg discomfort I've been fighting since last September. To me, it's more fun training to race than running for health. So, I'm starting to jack-up my treadmill runs so I might run a competitive race this spring.
I've only run an average of 80 miles per month since October. But I can and will soon do more. Sometime, I may need surgery on my back or legs, but it won't be due to excessive running. We'll see what the problem is, but in the meantime I'll train until I can do a competitive HM .
