2025 was another great year for the DSR and it seems 750 is the magic number for the village of Alto Pass. The 10th (YES, that is TENTH) year of the Dirty South Roubaix is coming up on March 7th 2026. Last year we sold out to the 750 registered in under 2 weeks, so don’t wait around if you want in on the event this year. We expect a sell out quickly again. Alto Pass has been so welcoming, that we will be back there again. Like years in the past, we are planning to offer the 100k+ as the main event of the day, but will also offer a shorter course for anyone who doesn’t want to tackle the full 100k. The short course is near half of the 100k. Don’t worry, it will still have a few hills and enough gravel The racers from the Half Dirty sure didn’t feel shortchanged after their race.
If you are looking for an awesome route, great challenge, killer scenery, beer, food and cool friends to hang out with for a day, come check it out.
Thanks for your interest!
Registration opens at 8:00am CST on 11/30/2025.

For the 100k event we will be splitting the results and awards into age groups. When you register, the website will place you into the correct category per your age and gender. There will still be awards for top 3 male and female overall, but will also be awards for top 3 in each age group. The age groups will be split into 10 year blocks.
