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.
