About the event

Random info.

This is the 31st year of the oldest ongoing gravel race in the midwest!!!

It takes place in Iowa's driftless region and has views that'll take your breath away.  

5 different routes are available this year.  25-40-60-100-200   Yes all routes include level B & C roads.    Remember, the Level C roads are private property and are NOT allowed to be ridden, except for on race day.

Count on roughly 1,000 ft of climb per 10 miles but you won't notice that, you'll be so busy enjoying the beautiful countryside.

The routes will be uploaded prior to the race so watch for those.  Will the routes be marked?  This year, we're only marking the 25 mile route.  That's right, the advanced racers are expected to use navigation and not get lost.  You know you can do it!

There will be aid stations on all routes. Outside aid is NOT permitted.  There will be a mandatory check point in Garber

Check in and bib pick up will start at 6:30 the day of the race.  

What surprises do I have in store this year?  Great question but the answer is, you'll have to wait to see.  

Will there be music and an awards ceremony?  YES!!!

Rules: Helmets are required.  No Karen's, Richards, or Kooks.  No support vehicles or outside support.  I don't want to see random vehicles out on the routes meeting racers.  Please. 

Chuck Norris would say, "don't forget to bring your legs, your friend's legs, your neighbor's legs, actually just bring all the legs there are.
