About this ride

This is the same climb as the Breckenridge record, started higher up. Overlap analysis shows 97% of this track lies inside the longer one; the difference is at the bottom, where this file begins on Boreas Pass Road itself rather than in town, about a mile and a quarter further up. Both finish at the pass. That makes it ten miles instead of eleven and 1,791 feet instead of 2,311. The surface change from pavement to compacted gravel arrives at about mile 3.7 here. Best if you want the climb proper without riding out through Breckenridge first.
