Say you're at a 100 person event, at about what age level do you start seeing less than 5 people of that age or older?

Funny I'm 45 and starting back up.

my guess is it falls off fast at mid 60's but that's an uninformed guess

Last year I talked with a 60-yo woman that said both her and her husband started entering triathlons in their late50's. I did my first tri last Dec at age 55.

I did my first tri about age 52 or 53, then a series of sprints in mid-fifties, and began Olys at age 61 and my first HIM at age 62.

thank all you who voted. It's kinda like I thought. just another pipe dream

Not sure I understand the poll but I just marshalled a 300-strong pool-swim sprint, and there were easily 4 guys and 2 women over 65, and I'd have pegged two of the guys as late 70s pushing 80. Legends.
