Ruidoso Grindstone Trail Half Marathon, 4M & 8.5M

Saturday, September 26, 2020 • Ruidoso, NM

Note: The 2020 race has been cancelled.

Set for its annual mid-summer running here in the Rocky Mountains of southeastern New Mexico, within sight of the slopes at the nearby Ski Apache ski resort, the Ruidoso Grindstone Trail Runs are the third of three half marathon events that take place in and around this mountain town during the summer.

The race unfolds along a series of trails that wind among the hills to the west of Ruidoso, a mountain resort town that’s home to more than 20,000 people. You’ll run

Runners will follow an out-and-back course for the race, which starts at Wingfield Park (at an elevation of over 11,000 feet above sea level) and then heads south along Grindstone Canyon Road to Resort Drive, where you’ll take a right and head west.

Once you make it off the roadway and onto the trails, you’ll follow a roughly counter-clockwise loop that goes up and down along the trails that surround Grindstone Lake, and which will take you out in the direction of Grindstone Mesa, before heading back around the lake.

Then you’ll head back into Wingfield Park for the race finish. Neither the half marathon nor the 8.5-mile run are open to walkers; but the 4-mile run is open to both runners and walkers.
