The Glacier Gorge Traverse and Rossiter's "Walk in the Park" are two related routes in Rocky Mountain National Park. They cover some of the same terrain, but they are different. The naming is confusing since the "Walk in the Park" traverses Glacier Gorge proper, while the Glacier Gorge Traverse encompasses Glacier Gorge, Loch Vale, Chaos Canyon and Tyndall Gorge.

The Glacier Gorge Traverse and Rossiter's "Walk in the Park" are 2 different but related routes in Rocky Mountain National Park. They cover some of the same terrain, but they are different.

Both routes start and end at the Glacier Gorge TH.

Cory Linfield posted the trail:

The Rainbow Trail is one of the longer hiking trails in Colorado, after the Colorado Trail and the Colorado section of the CDT. It runs roughly parallel to the Sangre de Christo mountains in the South Central part of the state, starting at one end south of Westcliffe and at the other end south west of Salida, forming an upside-down J. The trail is roughly 100 miles long with around 24,000 ft of gain according to a TOPO! map of the route. 

Jared Campbell keeps a (long!) list of Wasatch area FKTs here. Includes running, scrambling and some climbing as well.
