If you spend a bit of time in the adventure racing world you will find some ridiculously fit 50+ people. A decade or two ago some of these events/sports did not exist, certainly not with current participant numbers, so there are social, logistical, financial issues that affect any such study. People no longer just stop being active at 30 when they have kids, get a mortgage etc. It used to be just ex-athletes in the Masters category, but now it's much more widespread.
But this is a climbing site. Excluding older guided clients on commercially set up trade routes, think of:
- Last year's Piolet d'Or was (with others) won by Steve Swenson and Mark Richey, both alpinists over 50 who still climb hard, both high and technical.
- Marty Schmidt is around 53 and has climbed several 8000m peaks in fast times without oxygen in recent years. He runs a sub 3hr marathon and recently climbed a new route on Denali.
- Carlos Soria is over 70 and still climbs 8000m peaks, but normal routes with Sherpa support teams.
- And yes, I've no doubt Stevie Haston is still fitter and better than most 30 year old climbers.
