Hello everyone, glad I found this forum. Newbie here from Michigan. I am just about to purchase a hybrid - either a Trek 7100 or Giant Cypress or Cypress DX - anyone have any advice on these? Back in the 80's I had a road bike and participated in team triathlons as the 'cyclist' and did a fair amount of running. For the last 10 years didn't work out consistent, some cross country skiing, kayaking, very little biking. Now I'm 50 years old and need to lose 40 lbs, plus I have a permanent knee injury, Grade III Patella Femoral Lesion, possibly needing more surgery(had a knee scope in January) so the need for the hybrid and really need to get fit and lose the weight. Anyone have any training advice - miles per day/week, motivational advice??? Thanks
