Ready to charge straight up a sledding hill to start your race? Yep, we thought so. Race #2 of the Fox Valley Winter Challenge kicks off with a quad-burning climb that sets the tone for a seriously fun and seriously tough 8K adventure.
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.
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.
You can sign up for 2 or 3 races from any of the race websites, however here are their specific addresses:
