When I got to the bottom of the mountain, I'm pretty sure they had to replace the brake pads on my rental bike! My fingers were in tetany from constant pulling on the brake levers. And there were others flying by us (literally, not figuratively) bouncing from rock to rock at about 90mph like a bunch of deranged rabbits.
We made the mistake of buying a minivan years ago. Every fall I had to replace the brake pads because we made several trips in the mountains of WV.
This is a mountain bike trail near me (Alum Creek State Park near Columbus OH). Its about 5 miles away and now there are bike trails between my house and there. This was the second time I rode there, then rode the trail, then rode back home. But this was after not riding for a few months over summer when it got too hot and humid and we had heat advisories nearly every day.
I think the day of my crash I didn't eat enough before as I've been trying to loose some of the covid weight I've put on. Also I forgot to blow air in my Camelbak bladder when I put it in the freezer so the hose port was laying down in the water and froze up resulting in me not getting any water until I got to the trail. And I tried fewer stops. So I bet I was a little fatigued.
I bought a better helmet and have ridden paved trails a couple times since I'm still exercising.
The rest of my gear worked well, everything was covered in blood and dirt (well bloody mud) so I had to clean everything and took the time to re-inventory early, I usually do that during the winter months.
