Technically easy 14ers in the Sawatch Range that are usually climbed together. Doing both car-to-car is about 11 miles with 5800' of elevation gain (according to 14ers.com).
The ascent of Belford climbs 4500' over 3.75 miles, and there is a Strava segment. The Strava segment starts at the bridge across Clear Creek, rather than at the actual TH. That's a bit unusual for an FKT, but since the bridge is the lowest point maybe it makes sense for the ascent only.
