I was at the climbing gym this one time, working on a route. There were two copies of it side-by-side, as though for a race – ooh, fun! By this point I'd been climbing occasionally for about a decade and considered myself a beginner plus. I was never very good, being both overweight and lacking strength, but I did spend dozens of hours practicing.
My first time trying this route, I got halfway up but missed a jump. After a few more tries, I got past that part but got stuck further up, not having enough skill and strength to finish. Each attempt took me probably 5-7 minutes, and altogether I was on that route for about half an hour.
Then this thirteen year-old girl walked up and tied in next to me. She surveyed the route and checked her harness. Then, in one practiced motion, she leapt off the ground, reached for a hold above her head with one hand, and slapped the route timer start button with the other. I didn't even know there was a timer, so I was watching it curiously. It stopped at 8 second something. I was confused. I looked up, but she was already being lowered. I wondered to myself, wait, did she get pulled up by the auto-belay...? How does that work...?
Then she did it again. This time I watched. She flew up the course, jumping from hold to hold faster than I could even think, and beat her previous time by a few tenths of a second. It was like this video (https://www.youtube.com/watch?v=ktxxI_IPXjA) (that's not her, but similar route... maybe even the same route? not sure if it's a standard).
Despite a decade of climbing (mix of gym and outdoors, usually in small towns), it was my first time seeing a speed climber. I didn't even know that was a thing. Moreover, I didn't know the human body could even move that fast. Granted, I was never very fit, but I don't think I realized until that moment just how much fitter another person could actually be. In less than 10 seconds she easily finished what I couldn't do even in 400+ seconds – even though I'd been climbing longer than she'd been alive, lol.
It was humbling, astonishing, inspiring, and comedic to me all at once. It was very much one of those "wtf have I been doing with my whole life" moments. I'd always been the kind of person who was OK at a lot of things, never very good at any one thing, and to bear witness to such raw ability was... beautiful, if a bit discouraging, lol. I hope that by the time I die, I can become that good at SOMETHING in my life.
