🌲 Course Description

On February 21, we return to Oakhurst Forest Preserve in Aurora, where wide-open paths, winding woods, and a healthy dose of winter unpredictability await. The trails here roll and twist through some of our favorite terrain in the series—expect snow, ice, mud, or maybe a surprise combo of all three.

🥇 Participant Experience

The 8K is the middle challenge of the 2026 Winter Challenge Trail Series, sandwiched between our 5K and 10K races. Whether you’re running this as a one-off or as part of the Trail Series Combo, you’re in for a legit test of winter trail toughness.

• Finishers Benefits: All finishers will earn a custom medal and premium cold-weather swag.
• Bragging Rights: Plus bragging rights for conquering that beastly hill at the start.
• Series Progress: If you’re doing the full series, this race gets you one step closer to unlocking the full three-piece medal set and bonus gear.

👟 Prepare for the Challenge

So throw on your trail shoes, bundle up, and get ready to climb, cruise, and maybe slide your way through one of the most fun (and humbling) trail races of the season.
