About this race

2026 was another great year for the DSR and it seems 750 is the magic number for the village of Alto Pass. The 11th year of the Dirty South Roubaix is coming up on March 6th 2027. 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 11/29/2026.

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.
Example -
A 53 year old female would sign up for the 100k race. The system would put her in the Female 50-59 category. She will be competing for the overall award and the award for the 50-59 age group.
Some of you took advantage of the referral discount last year, so we are running it again this year. If you share the link provided to you after you register and 5 of your friends use that link to register, you get a refund of $10.
St. Nicholas Brewing Company is stepping up again to provide a beer to all participants. Each participant will be given a token for a beer. They can use the token at packet pickup, after the race or at any of the St. Nicholas Brewing Co locations in the future. Havisham Bourbon, Brew and Spirts House in Alto Pass will be offering additional drink options for purchase. We plan to have at least 3 different food trucks on site again this year and will give all participants a credit for the vendor of your choice.

Packet pickup the night before the race will be located at the St.. Nicholas Brewing Company location at the Carbondale airport (airport code MDH). They have an awesome restaurant and bar at the airport. With this spot close to the event, we hope to get many racers come to packet pickup the night before. We would love if we just had a few packets left for pickup the morning of the race.
