I hear ya! I’m 52. Not that young, either, but not quite old I guess. I suffer from Crohn’s disease and had a bit of a cancer scare last year. So I decided I wanted to do some kind of physical activity on my “new lease” on life so to speak. I met another guy in his early 40’s who said he had real high blood pressure. So he started doing these about a year ago and his blood pressure went back down to normal.
I despise running, but really enjoy target shooting. I’m a complete noob to the shooting sports, though. But running and shooting? Sounded like fun, so I figured I’d try it. Way tougher than I thought, and way more addicting! To say it kicked my butt is an understatement. I completely failed two obstacles, timed out and DNF’ed every stage but one, and kept asking myself why the heck am I subjecting my 52 year old body to this? I thought I trained sufficiently for it by jogging 5 to 7 miles with 15-20 lbs in my backpack, doing push-ups, pull ups, and weights, and even lost 10 lbs of body weight, but I still felt weak on some of the obstacle courses.
Anyway, there was a 58 year old guy there, too. I’ve heard of a guy in his 70’s do the Pecos Run and Gun (the venue that started this whole new awesome sport), but I don’t remember seeing anyone that looked to be that old at this one. Most looked to be in their 20s through early 40’s, and Texas A&M University even sent a team of their marksmen who looked to be college-aged and who completely dominated everything, including all the hard, physical obstacle course stages. The few older guys that did it walked most of it (you don’t have to run the whole thing). I jogged most of it and walked a bit in the real muddy, slippery parts, while reloading or just trying to catch my breath after a hard obstacle (climbing stuff while carrying about 20 or so lbs of rifle and gear).
The one I did also offered a 5K “sprint,” but it was sold out by the time I went to register for it. So I probably bit more than I could chew by signing up for the 10K. So glad I did, though. I learned a whole lot and what to expect of my gear in real wet and muddy conditions. Definitely want to do another one.
