Hi @jkbrooks, I would like to add my welcome to Connect along with @amandaburnett and others. I don't have HCM but do have hypertension and irregular heart beats - sinus rhythm with supraventricular ectopy. At 78 my pushing the exercise envelope days are over. I'm not able to ride a regular bike due to balance and a little fear of falling over but I do spend 30 to 60 minutes daily on my Teeter FreeStep Cross Trainer. I think it's great that you are able to do group bike rides and some touring on your own. I've thought about getting a 3 wheeler to ride around town but haven't made the plunge yet. I don't think anything can beat a nice easy going bicycle ride on a country road. I think you just have to find a balance that works for you to stay in shape and provides some fun and enjoyment doing it.
