Any kind of sport includes injuries. I have never participated in a sport that has injured me more than cross. I played soccer for 25 years without serious injury and regular cycling not so much either. I guess it is the running my 42 year old legs don't like. This time it is a pesky hamstring injury I had back in 2004 that has cropped up again.
I look doubtful for Rome this weekend and hopefully I can resume racing in 2 weeks. With my goals being nationals I would rather skip races now than then.
