I'm 67 years old, in reasonably good shape for a desk bound professional and I think I can do almost all of adam2's fitness test. The swim part might not be pretty, might have to float rest some, but I'd get it done. I'm not a bike guy, but given my regular distance walk of 11miles in 3 hours, including a steep 300' ascent and descent and some smaller hills, I think I can do most of the bike part. I'm not sure about the 100 miles in a day. Given that, for a man or women of average age, your requirements may be too low.

Bacpacjac's save with the Heimlich was praise worthy. WELL DONE! It reminds me of an event of my own, about 15 years ago. I became an EMT in around 1973. I also served 5 years , in the Seveties, as a volunteer on a very busy urban ambulance corps. We were taught choke save with a curved forceps. I actually did it once, successfully. But I have only read about Heimlich. At dinner that 15 years ago, I successfully employed the Heimlich maneuver to save my Mother- in -Law, who was choking on a clump of French bread. The "lady" in question, never a fan of mine, never thanked me. She did yell at her husband and my wife for not assisting her. She continued to dislike me, without cause, for the balance of her life. Worst mistake I ever made!
