Excellent RR! I did the Grit3 in early Aug with a friend and had a great time, though I should probably have ridden my bike a few times this spring. It turns out that mountain biking doesn't exactly get one in shape for Idaho singletrack on a loaded 525. I ended up getting really tired after a ridiculous no-trail day north of Challis and half-bailing for the last 2 days (of 6). It likely was also not the best idea to ride every single "Special Test" option. My riding partner Wiles posted a report: https://stappracing.blogspot.com/2019/08/the-wilds-of-idaho-ridaho-grit3-trip.html We only had Silkys so we had to jump a bunch of trees, though we did cut any smaller than about 10". This one looks familiar!
