Race Schedule

  • USA Cycling categories require a USAC license either as annual, 1-day beginner (cat 5 only), ‘experienced’ 1-day (former categorized racers), or a free junior license. 
  • USAC categories must hold a local race association license or pay $5 1-day fee.
  • Gran Fondo groups do not require a category.  

New racers can rock the 36 mile course either as a USA Cycling cat 5 or in the Gran Fondo category. Category 5 is a great opportunity to get your feet wet (and maybe muddy) racing in a group of similar ability while gran fondo can be a range of abilities.

We suggest pre-riding the course to test your equipment as well as riding in a group before you toe the line. And if you’re new, don’t hesitate to ask us questions. 

They could be pretty rough,  but by late May they are typically on the smooth/hard side with occasional rock here and there. We will post plenty of updates in the month ahead of the race on the road conditions. 

A road or gravel bike with tough ~27mm tires should do the trick, but part of the challenge with Roubaix is reading the conditions leading up to race day and making the call on what will yield the best balance of speed and durability for you. Stay tuned for more conversation on this as we get closer to race day.

You will be on open roads requiring your attention to vehicles and road signage. One aspect that makes Roubaix different from a Gran Fondo is our use of categorized start groups that are accompanied by a moto official, rather than a mass start of all participants. However if you get dropped from your group, please please stay to the right in order to not impede vehicles while also following all ‘rules of road’.

Follow the event website the week prior for the latest conditions. Dangerous snowy conditions will result in a cancelled or rescheduled event, however if it’s only wet and cold we run the race!
