Went out for a nice ride on my road bike. About 20 miles in 3 hours. Felt great for most of the ride, had chest pain about halfway through. A nitro tablet and 15 minute break fixed that. I'm definitely getting stronger and fitter and noticed a huge difference from just a few months ago. The weather was great and I had a light breeze to keep me cool. Scenery was outstanding and the bike path had enough hills to give me a challenge but not so many that I couldn't do it. I'm defying my cardiologists predictions and it feels great!!!
