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.

Russ Iverson posted the route:

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.

Wheeler Peak (13,161') is the New Mexico high point.  There seem to be a couple of main routes:  Bull of the Woods and from the Williams Lake TH.  The Bull of the Woods route has a Strava segment (ascent only), which records the FKTs as far as we know.

Another possibility is the "Wheeler-Kachina Traverse" (submitted by Tyler King):

The ascent of Mt Audubon from the Mitchell Lake TH is 3.9 miles with 2700 feet of elevation gain.  This is a VERY popular hike.  Note that you need a reservation to enter the Brainard Lake area of the Indian Peaks by motor vehicle during the peak season (mid-June through mid-October).

The Ascent and Round Trip have Strava segments.
