I'm 37 and have been into bikes all my life. BMX, MTB, Road and of course training and racing the last few years. I developed some hamstring/back pain late last season that has only gotten worse even though I've been doing PT and working with a doc. The diagnosis is a Spondylolysis of my L5 vertebrae. Basically, my L5 has got two cracks in it which is causing an instability in my back. I'm in a back brace currently trying to get the fissures to heal and the next step would be a spinal fusion. Either way, its looking like I'm not going to be able to race anymore. So, I guess my dilemma is what the hell do I do now? What would you do if you couldn't race anymore?
