Get ready to embrace winter, hit the trails, and take on the Fox Valley Winter Challenge Trail Series!
Returning for 2027, the Winter Challenge features three unique trail races across three of the Fox Valley's favorite forest preserves. Whether you're looking to shake up your winter training, challenge yourself on the trails, or simply enjoy some fresh air and adventure during the colder months, there's a race for you.
The series kicks off on January 23, 2027, with a scenic and beginner-friendly 5K at Dick Young Forest Preserve in Batavia. On February 20, 2027, the challenge continues with our signature 8K at Oakhurst Forest Preserve in Aurora, featuring the infamous sledding hill climb that has become a favorite (and sometimes dreaded) tradition of the series. Then, on March 14, 2027, we'll finish strong with a rewarding 10K at Hickory Knolls Discovery Center in St. Charles, bringing the Winter Challenge to an epic conclusion.
Each race offers its own unique terrain and winter conditions. From winding prairie paths and wooded singletrack to rolling hills and everything winter can throw at us, no two years are ever the same. Snow, ice, mud, frozen ground, or fast dry trails—part of the fun is never knowing exactly what awaits on race day.
Whether you choose one or two races, or take on the full challenge, you'll earn a custom finisher medal and branded race swag. Participants who register for two races will receive an additional exclusive bonus swag item. Those who commit to all three races will earn the complete Winter Challenge experience, including:
Three custom finisher medals that combine into one unique display piece
An exclusive bonus swag item
A premium series swag item available only to full-series participants
