The marathon became a permanent part of the Peterson Ridge Rumble after first appearing as an addition to its 20- and 40-mile races. Its result set and race distance remain separate from both siblings.
Course
Central Oregon trail carries runners along Peterson Ridge near Sisters. Dirt, singletrack and rolling ridge terrain call for trail pacing, with dry footing and repeated climbs more relevant than road splits.
Race-day weather
