New Mexico > Capulin Volcano Run Half Marathon, 10K, 5K & Fun Run
Folsom, NM  •  Sunday, September 29, 2013  •  Course Map

From the top of the 8,182-ft.-high mountain for which this race is named, runners will get the chance to see some of the most breathtaking views anywhere in New Mexico -- though it's quite likely many of them won't exactly be running while they're making their way along the mile-long trail that winds around the top of Mount Capulin, as the elevation and the climb will definitely be taking their toll by then.

That's just a few of the highlights that await the roughly 100 runners who trek to this corner of the American Southwest every September for the annual Capulin Volcano Run Half Marathon, 10K, 5K & Fun Run for kids, which marks its fifth annual running in 2012 as summer is turning to fall here in the region known as the High Plains of New Mexico, where colorful mesas and buttes are plentiful along the landscape.

The race takes place just south of a tiny village called Folsom, which is home to about 80 residents today, though it once boasted as many as 1,000 back in the first half of the 20th century, when farmers and homesteaders moved here to take advantage of this area's plentiful land. Later changes in the climate, however, forced many of those who'd come here to leave years later, as rainfall grew more scarce and the land turned over to become ranching lands.

Today, perhaps the town's signature attraction is the one that runners will climb come race day in late September, Mount Capulin at the Capulin Volcano National Monument -- an extinct volcano that is part of the Raton-Clayton Volcanic Field, which spans some 8,000 square miles across Colorado and New Mexico. Estimated to have last erupted more than 50,000 years ago, the volcano today rises more than 1,000 feet from its base to the trail that winds around the top of its cone-shaped cylinder.

For the race, runners will start on Highway 325 just south of the entrance to the national monument -- at 7:00 AM, to ensure that all runners are off the mountain roads by 9:00 AM, when the national monument area opens to visitors and car traffic. From there, runners head north and then turn right into the park area, where they follow the winding road up to the top of the Capulin Volcano. The fun -- if it can be called that! -- doesn't stop there, though.

Once runners reach the parking lot at the top of the mountain, they then head on to the paved trail that runs along the top of the ridge around the volcano. After climbing about 1,000 feet from the base to the parking lot, there's an additional climb of roughly 400 feet to the moutain's peak elevation, which lies along the trail between miles 3 and 4. After runners pass this point, it's (mostly) downhill from there, as the race course winds back down the volcano along the route the runners just ran, and then back onto Highway 325.

The remainder of the race route unfolds along 325 all the way in to Folsom, where runners will finish the race in front of the Folsom School House. This is also where runners are asked to meet, beginning at 6:00 AM, for the shuttle bus transportation to the starting line. The race proceeds go to benefit the Folsom Museum, which you can learn more about here.
