The Gladiator Course varies from event to event.

Gladiator Assault Challenge is the Midwest's premier test of endurance, speed, agility, strength, and mental stamina. Gladiator Assault Challenge obstacle courses are a series of physically challenging obstacles (some natural and some man-made) that individuals or teams must navigate. These courses will challenge you with running, climbing, jumping, crawling, balancing, and MUD with the aim of testing overall endurance.

The Gladiator Assault Challenge will be self-timed. We have seen over the past years that timing has not been a priority to the majority of our participants and therefore are going to focus those efforts on improving the course and obstacles.  There will be a clock at the finish line so you can check your time as you finish.


You may cancel your registration up to 30 days before the event and request to receive a full refund. Within 30 days, you can transfer your registration to another participant or receive credit for the 2025 race.  Within 7 days, no refunds or transfers. The transfer is only good for 1 year. 


Transfers and/or heat changes may be made by the registrant at the same website as the registration was made. No need to call us!

Can I Skip an Obstacle Because I Don't Feel Confident?

Yes, GAC asks that each participant makes their own personal risk assessment before each obstacle. GAC is all about having fun, testing your skills & limits, and camaraderie with fellow Gladiators. Each obstacle will test different mental and physical skills and there is no penalty for skipping an obstacle.

Anyone who is up for the challenge and is 15 and older on the day of the event is allowed to participate in the full Gladiator Assault Challenge or the 5K Charge (parental signature required for those under age 18). The last 3 heats of the day on both Saturday and Sunday will be a Junior/Parent Gladiator 5K Heat- available for anyone aged 9-14 to run with their parents.

Junior/Parent 5K Gladiator Challenge

GAC's Junior/Parent 5K Gladiator Challenge program allows the entire family to have a great day of adventure! Parents can run with their children who are between 9 and 14 years old.

A parent must be registered for the same heat as the junior.

Race Day Information


The race is held rain or shine - the more rain the more mud and the more fun it is! We will do everything possible to ensure all racers can get through the course safely - including delaying heat times, pausing the race, or postponing the race in the extremely rare case of extreme/unsafe weather. All weather decisions are made by GAC on-site staff. NO REFUNDS for inclement weather or if severe weather does not allow the event to be held.

The Rules

  1. You must understand and acknowledge that the Gladiator Assault Challenge is a grueling, difficult, and dangerous obstacle course and accept the risks associated therewith.
  2. You must comply with directions given by staff and medical professionals.
  3. You must be physically able to complete the course without harming yourself or others.
  4. There will be restrooms on-site, use them. Do not relieve yourself in any other location.
  5. You must understand that all water obstacles/pits vary in depth and you should not dive, jump or plunge into the water without first knowing the true depth.

What to Bring

Camera, towel and change of clothes, cash to buy merchandise, food, and beverages.

Packet Pickup

Packet Pickup will be available at the race site on race day ONLY. Once on-site, please proceed to the Registration Tents at least one hour prior to your start time to pick up your registration packet. A photo ID is required to pick up your race packet.

Be sure to allow enough time to check in (i.e. Parking, Packet Pickup, Bag Drop, Hike to Start, etc) before your start time. We recommend participants arrive AT LEAST ONE HOUR before their start time.

Bag Area

There is a bag drop area at the race site. It is a self-service area so do not store any valuables in your bags! Gladiator Assault Challenge, its affiliates, host sites, employees, and volunteers are not responsible for any lost or stolen items.

Course Clothing

Lightweight layers based on the outdoor temperature are recommended. Fast-drying and breathable fabrics are a must - you will be submerged in cold water several times! Some Gladiators wear gloves or tape to protect their hands. Avoid cotton which absorbs moisture and mud. Athletic shoes should fit snugly so you don't lose one in the deep mud partway through the course (duct tape around the shoes can help with this). Long pants and long sleeves that can get dirty (sweats work best). Bring WARM clothes to change into after the race, heated changing rooms are available.

Water Stations

During the event, there will be water stations set up approximately every 1.5 miles along the course (can be longer depending on the course). Water and fruit will be available after you cross the finish line. Plan ahead and bring a hydration system and/or energy supplements (bars/gels) if you think you will need them.

Showers / Changing Areas / Bathrooms

GAC will have cold showers, bathrooms, and heated changing rooms available at each event. They will be located near the finish chute. There's a good chance you will be very dirty!
