Friday I rode 27 miles from my house to Fern Truck Trail near JPL. In addition I bumped into some wildlife on the trail, thankfully none with sharp teeth! Also the MTB'ers are always surprised I ride a "road bike" up the trail!
To be honest I'm surprised other gravel bikes can climb this trail properly. I'm running a 2x 46:30t and an 11-42t + GoatLink, so my low gear is 30:42 and it's still a workout! Running a 1x gravel bike you'd need something like a 38t + 11-50t to match my gear ratio. I'm helping a friend swap out his groupset with something with better climbing, but even then, he'd have to run a fairly big cassette while still having a decent high gear when we ride the streets.
