What sets core4 apart from other gravel races?

Multiple surfaces on one bicycle in the same race. You gravel, dirt, single track and pavement and YOU determine the best bicycle to ride.

There are four distances - 100 miles, 60 miles, 40 miles or 20. They all contain gravel, dirt, single track and pavement. They will all be challenging.

The 100 and 60 mile routes and are podium eligible and have all for 4 surfaces including singletrack. The 40 and 20 mile routes are gravel centric and do not have singletrack.

The courses route through champagne gravel, the best b roads, amazing urban experiences, and super fast singletrack.

The races can be solo or a 3-person team and there are 18 categories per race distance.

The race format was modeled after the Rule of Three event in Bentonville, Arkansas. Tarmac, Gravel and Singletrack and what makes up that race.

core4 launched in 2022 and was Iowa's largest gravel event in Iowa. In 2023 the event grew by 30% with over 800 participants and 2024 ridership is capped and is already over one/thirdcapacity.

Why choose this experience?

The CORE4 experience is a testament to the enduring spirit of gravel racing (and more!) in Iowa.

You Finish. We all Celebrate.

Ever been to a race in Iowa? We cheer on everyone! This sense of community is no where more evident than core4.

The finish line is a chute of cheering spectators. There is live music playing. You get that last burst of energy as you approach the chute. You hurt and you smile all the the same time.

Get off your bike, take a photo, drink a cold one and cheer on the next finisher.

There is plenty of onsite camping, entertainment and camaraderie into the night.

Well Done - You'll sleep well.

We raced core4 in 2022 and 2023 and we are coming back for 2024!

Both years were simply hard AND fun at the same time.

The course kept us on our toes and the aid stations kept us satiated.

The after-party and camping was an experience all on its own. Listening to war stories and live music over food and drink with new and old friends are the best!

We LOVE to see that Iowa finally has a premier gravel event that appeals to and can handle the masses.

See you in August!


community. opportunity. recreation. engagement.
