Well scarey!
My 20 week plan starts next week. I am working on about 6-7 hours of run, bike, swim per week.
I had a mild set back of calf cramps/sprains. I think this reoccuring problem is actually coming from my back. Once again, not being well balance in a opposing muscle groups leads to injuries. I am working on my abs 3 days per week to strengthen my spine. Indoor biking is very difficult, but if I have an action packed movie to watch time passes by faster.
More later!
