5 years ago I partial knee replacements in both knees due to a degeneration of the cartilage. I was about 30 pounds over weight and out of shape from the inability to be active.After the rehab I embarked in a lifestyle change that was fitness oriented. I completed 5 sprint triathlons (racewalking the run phase). It became obvious to me that cycling was going to be my friend :) so I made the switch to cycling oriented.In 2007 I completed my first century 103.5 miles in 6:46:25. Two weekends ago I completed a century 116.25 in 6:31:42.I have also taken up racing. The photo I have included was from a crit earlier this year. At the age of almost 50 the young guys end up taken it to me by the end but I like to think I can make them pay early:)I race about 4-5 races a year seeing a steady improvement each race. I use my HRM almost constantly to monitor my training. I am about to do some off season testing using it to set up my training program for this off season with the hopes of doing well at the MN Sr. Olympics in June .As I have learned "a journey of a thousand miles begins with the first step"
