Quick update: On the advice of my Dr I've been doing some very light turbo sessions keeping my heart rate below 80bpm over the last few weeks (I found easy to control the heart rate on the turbo and wanted to get back in the saddle especially as I'd just had a bike fit done). Last week I had my first Cardiac Rehab session with some very light exercises (picked up a good warm-up routine). Had some good chats with the trainer and the cardiac nurse and they've said I'm good to get back out running and riding as long as I take it easy. So I headed out for my first ride since my heart attack on Saturday, a very relaxed and flat 11 miles. Felt really good to be back on the bike Going to take it easy with more relaxed turbo session and a few short slow runs.
