Date Change: We originally were planning a two-day event for Saturday & Sunday. As of May 1, this is now a one-day event. Saturday only.

The Cerus Fitness Festival is a local celebration of health & fitness. This event brings local businesses from the Town of Frederick to Centennial Park to promote nutrition, movement, and fitness in all forms. Participants will experience free talks & demonstrations, local food vendors, and fun fitness challenges for all ages.

Showcase your fitness by purchasing a ticket to participate in a 5k run (1 mile kids run), an obstacle course race, and/or a strength-based event.

💪 free fitness challenges
📣 free talks & seminars about health & wellness
🧗 Cerus obstacles that you've come to know & love
🏃‍♀️ a fast, flat, 5k course that runs through around the Town of Frederick
🍲 a food & coffee truck

Check In & Bibs

Please arrive at least 20 minutes before your scheduled event. All participants must check in at the check-in tent on Saturday morning. There is no check-in on Friday.

CHECK-IN OPENS at 6:00am

5k & 1-mile runners
You'll receive your race bib & timing chip when you check in Saturday morning.

OCR & Strength Games athletes
You will receive a colored wristband to indicate which event you are participating in. Please keep this band on your wrist as long as you are at the festival. You'll need it to gain entry to the course that you're participating on.

Upon check-in, you will be able to select a 30-minute window in which you'd like to participate in the OCR course and the Strength Games. This is for your officially timed run, in which you'll have a judge assigned to you.

After all athletes have had a chance to be timed/judged one time... or there is a break in the action... you are welcome to make additional attempts at both the OCR course and Strength Games workouts. If you'd like your attempts to be official and added to the leaderboard for a chance at the podium, make sure you flag down a judge/volunteer so that we can verify your attempt.


NOTE: The Strength Games was moved from Sunday to Saturday. The festival is now a one-day event, Saturday only.

🤸 400m Obstacle Course

The 400m OCR course will begin shortly after the 5k race has finished.

The 400m obstacle course race will consist of many traditional Cerus obstacles, including:

  • hanging implements (rings, monkey bars, etc.)
  • carries (sandbags, atlas stones, etc.)
  • climbing over walls
  • crawling under various things
  • jumping from object to object
  • slack lines, seesaws, and more

You can opt to tackle the course solo, or challenge your friend and go two at a time. All times to our digital leaderboard. Once all participants have had an opportunity to go through once, we'll open it up for second attempts.

💪 Strength Games

5/1: IMPORTANT UPDATE: The Strength Games has been moved to Saturday, after the 400m OCR event. For those who have already signed up for Sunday, we'll contact you soon about options if you can't make Saturday.

The Strength Games will balance out the 5k and obstacle course race. We'll have 5 tests of strength that comprise the Strength Games. Many of these tests will include some type of heavy implement or odd object, and you'll move right from one test to the next. You will be scored on each test, and your scores will be combined to give you a total score for the Strength Games.
