Official Rules & Standards →

Test your speed, strength, agility, and endurance on your own schedule in this 3.5 week challenge. The top athletes in the CerusBrix Open will advance to semifinals. We'll make one more cut and invite at least the top 6 athletes to the CerusBrix Championships on June 23-24, where athletes will compete for thousands in cash prizes.

The Open category is for all athletes. Anyone can enter.

The Masters category is for athletes 40+ (age as of June 23).
Only the Open category carries the cash prizes but all divisions will have a semifinal and championship field.

Even if you are 40+, you may still chose to compete in the Open division. It's entirely up to you.

Registration is open through April 14th.

How It Works

There are 4 total workouts to be completed over a 21-day period – speed, strength, agility, endurance.

  • All workout descriptions have been released
  • On February 23rd, we'll release the official movement standards & rules.
  • Workouts will be performed at Cerus Fitness and scored by a judge that is provided for you. You will sign up to schedule a time to come in.
  • The Speed workout may also be performed at any location of your choosing, but it must be video taped and submitted for verification.
  • All 4 of your scores will be combined to give you a final score. We'll use this to determine who moves on to Semifinals.

The Workouts

Here are the 4 workouts for the 2024 CerusBrix Open:




Scheduling / Retesting

You may perform any of the 4 workouts at any time between April 1-21, provided you schedule a time with a Cerus judge.

Schedule a test →

If you'd like to retest a workout and submit a new score, both workouts must be completed within the following windows:

  • Speed: March 23-29
  • Strength: March 23-29
  • Agility: March 30- April 6
  • Endurance: April 7-13

Only 1 retest is allowed per workout.

Speed can be tested at Cerus Fitness or tested on your own and filmed. If you test outside of Cerus Fitness, a video submission is required.

Leaderboard / Scoring

Each workout in the CerusBrix Open has a possible score of 1,000 points. First place receives 1,000 points. Each place then drops by 25 points. So second place is worth 975, third place 950, and so on.

Your Open scores will be taken into consideration for the Semifinals, but the Semifinals workouts will be weighted much more heavily.

All scores reset for the CerusBrix Championship. Everyone starts at zero. We simply use your rank in each workout as your points, and the lowest score wins.

We will update the leaderboard at least once a week, on Wednesday, so you can see where you currently stand. We may choose to update it more frequently. 

The leaderboard will be posted on April 5th on our website.

Keep an eye on our Instagram & Facebook pages for impromptu updates.

Semifinals / Championship

The top athletes in open and masters categories of the CerusBrix Open will advance to Semifinals. We'll take roughly the top 66% of athletes in the Male Open, Female Open, Male Masters, and Female Masters divisions. After all scores are final for the CerusBrix Open, we will announce the semifinalists and alert them via email.


Semifinals will occur on two separate Saturdays. You will be required to attend one of the days.

  • April 27, 2023
  • April 28, 2023

Semifinals will be comprised of at least 2 workouts. You will be scored on each workout... those scores will be combined... and that will be your final score for the Semifinals. Your scores from the CerusBrix Open will also be taken into consideration when determining who makes it to the Championship.


The CerusBrix Championship will be held on Friday night, May 17th and Saturday, May 17th, 2024.

  • At least 6 Open division males & 6 Open division females will be invited to the Championship
  • At least 4 Masters division males & 4 Masters division females will be invited to the Championship

Depending on participation, we may decide to invite more.

Cash prizes will be awarded to the top 3 men & top 3 women in the Open division. Masters athletes will be recognized on the podium and receive 1st, 2nd, and 3rd place medals, but are not eligible for prize money.

Official cash prize amounts will be announced on April 15th, but the minimum payouts for top males & females will be:
🥇 $1,000
