Approximately 40k ft. gain/loss (80k ft. change).
MORE SINGLE TRACK
Effectively zero asphalt. Most of the groomed dirt county roads have been eliminated and replaced with steep, technical single track trails and double track Jeep roads.
The average elevation is over 10,000 feet. The new high point is Fort Peabody at 13,365 feet.
NEW START DATE / INCREASED CUTOFF
To reflect the increased difficulty, the cutoff has been extended to 50 hours and the start has been moved up to Friday, July 31st at 4:00 AM. This way you aren't having to convince a pacer to help you on a Monday.
The second annual Ouray 100 Mile Endurance Run is back. And back with a vengeance. Touring the Ouray District of the Uncompahgre National Forest, the O100 is situated in the high and rugged San Juan Mountains (Rocky Mountains) of Southwestern Colorado. Between the hot springs, the brewery, the views, and the friendly atmosphere, the "Switzerland of America" will not disappoint.
