This is my "local" peak (living a couple hours north of the park) and I've been wanting to go sub-1:40, so made my attempt today as a workout in my buildup for summer ultras. I was feeling pretty healthy and injury free, so had a good day (even if holding some residual fatigue from recent heavy training the last couple weeks). It turned out to be a nice day, not nearly as hot as it was when I came down to do a long run a few days ago, but it was getting a bit warm (81 F) by the end. Now that the summer heat has set in, the trails in Big Bend are much quieter than in the winter and spring months, which was nice. Today I hit the peak in just over 1 hour, spent ~30 seconds snapping a photo of the benchmark, and then took just under 39 minutes to descend. This attempt was unsupported and I carried one 18 oz handheld with Roctane and had one gel near the top. See my previous report for details about the route.
My Garmin Fenix 7s recorded 9.95 miles with 2517 ft elevation gain at an average elevation of 6514 ft.
Also, I was having trouble uploading photos here, but you can see them at my Strava link.
