The Flagstaff Loop Trail seems to be still in process, but there appears to be enough on the ground for people to begin reporting FKTs. ~45 miles

The Teton Crest Trail runs from the Phillips Pass trailhead on Teton Pass to String Lake via Paintbrush Canyon, about 38 miles.

Hello!  I'm planning a long run starting tonight from the Alamo in San Antonio to the Capitol building in Austin.  It will be self-supported, using stores/restaurants along the way.  My route will for the most part follow I-35 or parallel to it.  Remains to be seen just how challenging it will be to run along the access road.

I plan on Hiking the Rampart Range, from North to South. Far as I know, I don’t think anyone has done it…or recorded it on the web at least. Anyway, what I believe is to be the furthest North of RR is the where the S. Platte river meets Chatfield State Park. On the southern end, I would think it is where the RR runs into Ute Pass… or HWY 24. In theory, that could be anywhere along that border. But the most southern part of RR, and where it hits Hwy 24, is where Rampart Range Rd. Spills into Manitou Springs.
