First off I'm not trolling or trying to start a flame war. I have a legit question which I'm hoping you can help answer due to your own experience or that of someone you know or have heard about.
I'll turn 60 in October.
Type 2 Diabetic with blood sugar under control via meds.
Triple bypass in 2004.
Stent put in my R Femoral artery last year.
Overweight but working on it.
Doctor suggested riding again (I used to about 20 years ago) as a way of weight control and increasing endurance. With enough work and effort on my part over the next year would i be able to keep up with the pack, even the back of the pack, in local 4/5 35+ crits, or am I out of my mind.
