The WORS Border Battle is a landmark mountain bike race in the Wisconsin Off-Road Series (WORS), North America’s largest state mountain bike racing series. Traditionally a Wisconsin-based series, the event made history in 2025 by crossing state lines into Illinois to settle the ultimate question: which state has the fastest riders?

Course Description

Located at Atwood Trails within the Rockford Park District's Atwood Park, the course offers a unique "riverbed" racing experience.

Terrain: Unlike the rugged ski hills typical of Wisconsin WORS venues, Atwood is characterized by mostly flat, fast, and "flowy" trails.
The Route: The course utilizes approximately 5 miles of multi-use natural surface trails that run along the scenic Kishwaukee River.
Elevation: Expect roughly 300 feet of elevation gain per lap, making it a high-speed race where "having your body on point" is critical to maintaining momentum.

Event Highlights

State vs. State Showdown: Points from all riders are tallied to determine a winning state, making every participant a contributor to the Wisconsin vs. Illinois rivalry.
Double Championship: The event serves as the official Illinois Mountain Bike State Championships, where Illinois riders compete for state titles across Elite, Sport, and Comp categories.
Inclusive Categories: WORS caters to all levels, from the "Kids Comp" for 7-14 year olds on a beginner-friendly 3–6 mile course to the "Newbie" category, which is often free for first-time racers.
Economic Impact: The race is a major regional festival, typically drawing over 50 teams and 1,500+ riders and spectators.
