    Course

    The Sangre de Cristo course

    Every distance starts and finishes at Music Meadows Ranch beside the Grape Creek Trailhead outside Westcliffe, on the western flank of the Wet Mountain Valley. The races run almost entirely on the Rainbow Trail, a mostly double-track trail built by the Civilian Conservation Corps along the boundary of the Sangre de Cristo Wilderness, and the festival uses about 21 miles of it.

    Read the full course notes

    On recent editions each race has opened and closed with an out-and-back on the USFS road toward Music Pass, the high point at 11,412 feet. The access trails to the Horn Creek and Venable aid stations are rocky and technical, the trickiest footing of the weekend. The 100-mile, 100K, 50-mile and 50K run on Saturday, the 27K and 8-mile on Sunday, and the 100-mile (capped at 50 runners) has a 38-hour limit.

    Weather on race day
    Late September in the Sangre de Cristos swings from an average low near 35 °F to a high near 70 °F, and the first snow of the season can arrive around race weekend. Rain, wind, hail and storms are all possible, so the long distances need warm layers for the night and a waterproof shell. The aspens are just starting to turn, which makes this a beautiful weekend to be on the trail.

    What to train for

    Train for rocky mountain trail at altitude: long runs on technical terrain plus a weekly hill session of 6–10 climbs of 3–5 minutes at a strong, steady effort.

    Practice a long climb and descent of a big pass, since the Music Pass road comes both early and late.

    For the 100K and 100-mile, run at least one session through the night with your headlamp and full cold-weather kit, and rehearse eating on the move for many hours. Runners from low elevation gain a lot from a few days in the valley before the start.

    Taper

    Tapering for the Sangre de Cristo

    Start the taper two to three weeks before race day. Cut your weekly volume by about a third, then by half in race week, and keep a few short efforts at race pace so your legs stay sharp. The course is hilly, so keep one short hill session in the first taper week to keep the climbs familiar. With the race on September 25, 2027, your taper starts around September 7, 2027.

    Sangre de Cristo training questions

    How long should I train for the Sangre de Cristo?

    Most runners give a 100-mile twenty to twenty-four weeks of focused training on top of an existing base. The plan above counts back from your actual race date, so if you have less time than that it builds the best plan the remaining weeks allow rather than pretending you have longer.

    Is the Sangre de Cristo course hilly?

    Hilly. Every distance starts and finishes at Music Meadows Ranch beside the Grape Creek Trailhead outside Westcliffe, on the western flank of the Wet Mountain Valley.

    What is the weather usually like at the Sangre de Cristo?

    Late September in the Sangre de Cristos swings from an average low near 35 °F to a high near 70 °F, and the first snow of the season can arrive around race weekend. Rain, wind, hail and storms are all possible, so the long distances need warm layers for the night and a waterproof shell. The aspens are just starting to turn, which makes this a beautiful weekend to be on the trail.

    When should I start tapering for the Sangre de Cristo?

    Start the taper two to three weeks before race day. Cut your weekly volume by about a third, then by half in race week, and keep a few short efforts at race pace so your legs stay sharp. The course is hilly, so keep one short hill session in the first taper week to keep the climbs familiar. With the race on September 25, 2027, your taper starts around September 7, 2027.
