Mesa Trail roundtrip completed today (June 25) - first reported female time (I have to imagine plenty of ladies have done it faster and I fully expect this to get beaten easily).
North to South watch time = 1:27:03
(From the gate at the bottom of Bluebell Road to the South Mesa parking lot; I took the true Mesa trail and not the cutoff near the south end of the trail)
Round trip total watch time = 3:03:51
(including a short break at the south end)
All unsupported. That's a fun trail, nice climbing, great variety, excellent signage, a bit rocky here and there, and wide open running on both ends. Wonderful views of the Flatirons.
Tracking file for my InReach and a couple photos attached.
