XDirty 130

MGRS Ultra

The XDirty 130 course is simply amazing.  Pristine woods, amazing river views and kids' bikes strewn in the middle of the road.  These are just a few of the sights you may see on this gravel adventure of a lifetime. 

The XDirty 130 is a solo endeavor.  No outside assistance providing fluid/food is allowed in the XDirty 130.  If you break down or become injured during the XDirty 130, please contact your rescue crew to be picked up. The organizer or sponsors are not responsible for rescuing you.  Please also notify us if you are dropping.  There will be a phone number on the back of your race plate that you need to text if you drop.  It is very important for us to know if you drop so that we can account for everyone at the end of the day. 

In 2024, we will continue to work with JDRF, who will be providing rider and bike transport back to the start/finish in the event that you break down or cannot continue on your journey.  A donation of $45 to JDRF is required to reimburse them for their time.

We can't thank Matt Acker enough for his in depth knowledge of everything gravel.  Matt was quite involved in the Dirty X130 course design.  Thank you for being so awesome and gracious Matt!

In a time not so long ago, during the 1840's, Saranac lumberjacks felled trees with grit and determination using hand tools.  The monster trees were delivered to a saw mill in Saranac, MI, where the wood was cut for the furniture and construction industry. In that same vein, XDirty 130 riders that complete this extremely challenging 130 mile course within 9 hours will be awarded the coveted XDirty 130 HATCHET. Not only is the hatchet a work of art to admire daily, it can (and should) be your companion on your next adventure.

Don't think you can finish the XDirty 130 in 9 hours?  Have no fear, you won't leave without something!  Finishing this beast of a course is a huge accomplishment and reason to celebrate.  Riders that take longer than 9 hours to finish will still take some finisher bling home to reward them for their hard earned day in the saddle.

All XDirty 130 registrants will also take home a Dirty 30 Gravel t-shirt, a unique XDirty 130 patch as well as well as a custom skull cap to keep your noggin warm!!  

Gas stations are available at mile 80 in Vermontville and mile 85 in Nashville.  There will be a water refill station in Nashville.  Refueling stations used on the 30 and 50 mile will be made available to XDirty 130 riders (miles 114 and 126). 

There will be police in place at select intersections outside Saranac from 7 AM to 2:30 PM (in Ionia County only).  It will still be critical that the rules of the road be followed.  Front and rear lights are required.  There will be a timing point on the course to assist with tracking riders on the course.

Start time is going to be 7 AM.  The cutoff time is 12.5 hours after that, at 7:30 PM.  Sunrise on April 13, 2024 is at 7:01 and sunset is at 8:21.  Cue sheets of the course can be downloaded below.  It is strongly recommended that you have the course uploaded into your GPS as well as bringing the cue sheet with you.  Stuff happens, things break, so have a backup.

We created a private XDirty 130 facebook group to discuss conditions, nutrition, gear and ask questions.

The XDirty130 is part of the Michigan Gravel Race Series (MGRS) and designated as the Ultra Course.
