Mtwarden, 40 miles is a long long ways. Was that flat road miles or up/down trail miles? I ran a marathon a couple years ago and can't imagine going farther than that. You're a beast.
thanks- mountain miles technical single track (lots of rocks, roots, etc conspiring to trip you up) and roughly 3000’ of gain, 10,000’-ish total
no sleep (I was up at 5:00 AM Friday morning) and a night venue definitely added to the “fun”
