“A 100K and 55K mountain trail running race in the beautiful San Juan Mountains!”— Rich Price
Race - Aug 3, 2019
Proceeds from the race benefits Big Brothers Big Sisters of Southwest Colorado!
Each runner must carry at least 40 oz of water carrying capacity. Aid stations will not have cups for water or electrolyte drinks.
Parking race morning—on the streets of Silverton near 12th and Greene Street
Spectators and crew are only allowed at aid stations 1, 4, and 6.
South Mineral Creek has four creek crossings that will likely not get you wet this year (2018) because of super low snowmelt and water levels, but in other years you would get wet on these crossings. The Rico Silverton section is also probably the most technical descent of the whole course; about a mile section is pretty steep and rocky. This is about a mile above Aid Station 5 and 0.5 miles below the CT.
You'll get wet crossing Cascade Creek before Aid Station 4. It will be low this year, but in other years the water could be up to your knees.
Aid Station 1: Mile 11.4 at the top of Molas Pass in the paved parking lot.
Aid Station 2: Just past the junction of the Engineer Mountain Trailhead and on the Colorado Trail at mile 21.93
Aid Station 3: At the end of Cascade Divide Rd (FS Rd 579) at mile 28.78
Aid Station 4: At the Engineer Mountain Trailhead on the southern base of Engineer Mountain just off Hwy 550 at mile 37.06
Aid Station 5: At the southern terminus of S. Mineral Creek Rd at the Rico – Silverton Trailhead at mile 50.17 / 25.33 (This is also the third aid station for the 55K.)
Aid Station 6: At Anvil Campground where Mineral Creek crosses S. Mineral Creek Rd, mile 50.09 and 31.25
