Aiming for 2 hours, ended up a few minutes shy. Lots of climbing. 1750 feet and 24 miles. It was either up or down, not a lot of flat.
Ended up on a gravel path for a bit, but went with it even on my 23s. Wasn't terrible, mostly small stone, some sharp but no issues. Very bumpy though, had to keep the speed down. Luckily it was flat, not sure what 10% on that would've been like on my bike.
Heart rate was suppressed the whole time, but legs felt pretty good. Cold at the start, wishing I'd had warmers on, only 58 or so.
