Thanks to everyone again. I think this was a good topic to discuss on this forum and how it relates to mountain and road biking; so others with health issues know that we shouldn't be afraid and let it stop us. It just takes a little bit more planning and consideration and that there are plenty of options out there. I actually went back and hiked the trails this morning and can't wait to go back on my MTB. I will bring a friend

Tulip, yes I did inform the group leader and he was very supportive and an EMT. He rode back with me to make sure I stayed safe while the other leader stayed with the others. But, for reasons which Becky mentioned, I would not tell the whole goup.

Becky, thanks for the book and I will be in touch with you. I will see if I can try to find the book.

Thanks again to all.
