John Marsh fractured his left collarbone on April 16, had surgery on April 27 and got back on the trainer May 6. He’ll be stuck on the trainer until June 4, at least, and after a trip with his family, he’ll have just four weeks to finish training for the Tour of Wyoming July 17 – 22, 355 miles with 32,620 feet of climbing. John had very little exercise for 18 days between the crash and surgery, except for walking. Further, his body had the trauma of an accident and surgery with general anesthesia. After any significant amount of time off the bike due to an injury or anything else, your comeback should be step by step.
