Crossfit athletes v. Hyrox athletes

and

Feb 28, 2025

Many top CrossFit athletes are now experimenting with — or transitioning entirely to — Hyrox. Tia Clair-Toomey, a 7-time CrossFit Games champion, is competing in the mixed doubles division this weekend in Hyrox Brisbane. Ricky Gerard, who finished 3rd in the CrossFit Games in 2022 and 7th in 2024, is competing in the solo pro division. 2024 CrossFit champion James Sprague competed in Hyrox Las Vegas. Other elite CrossFit competitors who have competed in Hyrox include Kristi Eramo O'Connell, Chandler Smith and Sam Briggs.

While many current and former elite CrossFit athletes have performed well in Hyrox races, none have yet become elite Hyrox competitors. Both sports combine endurance and functional fitness movements, but they are fundamentally different sports. Excelling in each sport requires different athletic capabilities and training methodologies.

Dr. Gommaar D'Hulst, a sports scientist based in Switzerland, details some of the key physiological differences on his YouTube channel, WOD Science. D'Hulst explains that because a Hyrox race requires 60-90 minutes of sustained output, the major training focus needs to be conditioning. CrossFit, meanwhile, typically involves 20 minutes or less of high-intensity work, putting a premium on power.

While CrossFit requires an extremely well-developed anaerobic energy system, which the body uses for short bursts of effort, Hyrox is primarily aerobic. Even the strength-based stations in Hyrox, like the sleds and lunges, are aerobic. D'Hulst says that, based on his testing, the aerobic base of a typical high-level CrossFit athlete is "not that high." This isn't to say a CrossFit athlete could not develop the aerobic base necessary to compete at the highest levels of Hyrox, but it will take time.

How to analyze your next Hyrox race

In the three months leading up to the Hyrox World Championships in June, there are 30 Hyrox races all around the world.

Hybrid Athlete of the Week: Ronald Bradford

Name: Ronald Bradford
Age: 47
Hometown: Richmond, Virginia

When did you start hybrid racing? March 2024, when I did my first doubles race in Washington DC. I decided to do my first race after watching my gym friends compete last year in NYC/New Jersey.

Favorite race to date? Hyrox NYC this past June at Pier 76 was my favorite race because we were able to improve our time. Special shoutout to my partner Gabe who lets me sign us up for races without asking first.

Race goal? My next race goal is to do my first solo Hyrox. If you know me, I never wanted to do this solo, but things change.

Favorite station? Surprisingly, the burpee broad jump. We have a love-hate relationship.

Least favorite station? Sandbag lunges and skierg equally.

Something you wish you knew when you started racing? Although my friend Amber told me I needed to run more, I didn’t. Now she has me signed up for four races leading up to Hyrox because I see how much running is a game changer for the races.
