I am still a Clyde my Job and life Situation has forced me to return to working more and riding less. I want to toss in a bit of running as well but feel after a L4-5 back surgery that I am still too heavy to run anything that would be actually called running. So my question is what weight is a good target to start thinking about it again I am still in the 310 range and am down 20 pounds from my all time high. I carry the weight well but am wanting to think about again when I'm in the 240 range as the less the impact on my back the better. Where did you start running of you did and do you think you started too soon or waited to long?
