I hope more is found about Coasting's leaving us much too early.
Early 40's if true is much too young but most of us have known others that have died much younger of heart disease....I have known a few in fact.

What I don't understand and hopefully somebody at some point can shed some light, is I am hearing two very conflicting things.

History of heart issues in conjunction with rigorous cycling as reported here by his hill climbing. Nothing more taxing on a heart. Most of us have experienced that heart is about to explode feeling when participating in a grueling, long steep climb in fact. I don't understand why he would take this chance if he knew he had a heart issue. Perhaps this will never be known.
