Get ready for a classic cross-country experience at the Expo Park XC on September 20, 2026, held in Aurora, CO. This event offers an exhilarating day of racing for all ages and abilities, with distances including a 5K for all ages, a 4K for those 14 and under, 3K options for 10 and under and 12 and under, and a 2K for 8 and under, plus a free 1K for the youngest runners. Typical race day conditions in late September feature comfortable highs around 79°F and lows around 48°F, with a low 5% chance of precipitation, providing ideal weather for hitting the grassy courses.

The Expo Park XC boasts an authentic, old-school cross-country course that is primarily grass with gentle undulations. Runners will navigate a wooden footbridge, several concrete path crossings (spikes are welcome but the paths remain uncovered), and a small creek crossing, along with fun bale jumps that add a unique challenge. The 3K and 5K races begin with a 1K loop before tackling additional 2K loops, while the 4K involves two circuits of the 2K loop. Starting and finishing at South Moline Street and East Exposition Avenue within Expo Park, this event promises good, old-fashioned cross-country fun for individuals and teams alike.
