The Dirty South Roubaix 2026

Prepare for a true test of grit and endurance at The Dirty South Roubaix 2026, marking its 10th anniversary on Saturday, March 7, 2026, in the welcoming community of Alto Pass, IL. This celebrated gravel event draws participants from across the nation, famously selling out its 750 spots rapidly in previous years. Riders can choose their challenge from the main 100K+ course, or the equally demanding Half Dirty, which covers approximately 50K. Additionally, categories for Single Speed 100K+ and Tandem Team 100K+ are available for those seeking a unique competitive edge. Starting and finishing at the Alto Pass Village Park, the race promises "pain and suffering" alongside an "awesome route, great challenge, killer scenery, beer, food and cool friends to hang out with for a day".

The course itself is a quintessential "Roubaix" experience, featuring a dynamic mix of surfaces including buttery smooth asphalt, chipseal, chunky gravel, mud, and dirt, all set amidst the stunning vistas of the Shawnee National Forest. Unlike much of the flatter Midwest, southern Illinois offers "relentless elevation changes" and "beastly inclines, both steep and relentlessly long," with some challenging 20% grades on soft gravel that may require dismounting. Typical race day conditions in early March see highs around 53°F and lows around 34°F, with a 15% chance of precipitation, so prepare for variable early-season weather. Aid stations will be strategically placed, with two sag stops for the 100K+ and one for the 50K, providing hydration and even mechanical support from Bike Surgeon mechanics.

What truly sets The Dirty South Roubaix apart is the grassroots support from Alto Pass, a small village that fully embraces the influx of cyclists, creating a fun and vibrant atmosphere with cheering crowds and even unofficial beer stops. Participants can enjoy food trucks and a token for craft beer from St. Nicholas Brewing Company post-race, adding to the camaraderie that defines this early-season challenge. For a memorable ride that tests your limits against incredible natural beauty, The Dirty South Roubaix is an unmissable event.
