I started riding road bikes just before age 40 and continued until age 54 or so. Rode a lot locally in eastern CT, did a century each year and once rode from Lake Sebago in ME back to CT. Got to be a fairly good recreational rider. Then, at age 54, I just sort of stopped. Last year I decided to get back on the road and did about 1100 mi. during the season. Since I started out weighing 190 lbs. (should be 170-175 lbs) I truly suffered, especially in the hills. Last winter I took spinning classes 3Xwk. and have about 1000 mi. in so far this season. Problem is that even though I've lost 5-7 lbs since May, and have increased my average speed about 2-2.5 mph since May, it doesn't seem good enough to me. I think I should be going faster and climbing hills better. Is this an age thing? Am I training incorrectly? I could really use some advice.
