A demanding fitness race built around running, sleds, lunges and 100 punishing wall-ball throws has found a local training hub at Functional Fitness of Falls Church.
The gym at 2840 Graham Road offers three weekly classes tailored to HYROX, an indoor competition that combines eight one-kilometer runs with eight workout stations. It has been a HYROX affiliate for more than a year and has trained clients in the style for several years.
The growing sport provides a more intense option as other residents prepare for the 2025 Falls Church Fitness Challenge, scheduled for April 1-30 with activities ranging from yoga to team sports.
Functional Fitness co-founder and coach Kavon Atabaki has nearly 20 years of industry experience. His credentials include certifications in kettlebell instruction, body-weight training, functional movement and personal training.
Eight runs and eight grueling stations
HYROX began in Germany in 2017 with founders Christian Toetzke and Moritz Fürste and an inaugural field of 650 competitors. By 2024, participation was expected to surpass 175,000, with races held in more than 30 cities across at least 11 countries.
The name reportedly blends “hybrid” and “rockstar,” rather than serving as an acronym.
Every full HYROX race follows the same format. Competitors run one kilometer before each of eight exercise stations:
- A 1,000-meter SkiErg.
- A 50-meter sled push.
- A 50-meter sled pull using a long rope.
- Eighty meters of burpee broad jumps.
- A 1,000-meter row.
- A 200-meter farmer’s carry.
- One hundred meters of sandbag lunges.
- One hundred wall balls.
Standard farmer’s-carry weights are 50-pound kettlebells in each hand for men and 30-pound kettlebells for women. During the lunges, competitors carry a sandbag and must touch a knee to the ground with each alternating step.
The final station requires men to throw a 14-pound ball at a 10-foot target and women to throw a 10-pound ball at a nine-foot target. Each repetition begins with a squat to approximately knee height. Women previously completed 75 repetitions, but the requirement was increased to 100.
The average finish is said to take about 90 minutes, while elite competitors can complete the course in roughly 58 minutes. Atabaki said many recreational participants may need closer to two hours.
Washington, D.C., was scheduled to host the HYROX Open North American Championships at the Walter E. Washington Convention Center on March 29-30, 2025. The sold-out competition was expected to use the building’s large exhibition floor.
Competitors enter in waves, with about 25 people released every 10 minutes throughout the weekend. Atabaki described an energetic scene filled with racers, spectators, warmups and cheering at nearly every stage of the course.
A predictable test with several entry points
Atabaki said the sport’s consistency is one reason it has expanded so quickly. Unlike an obstacle course with unknown challenges, HYROX uses the same stations in the same order, allowing athletes to compare performances and measure improvement much as runners track their 5K times.
The sport also offers full-course, partner and four-person relay divisions. Relay teammates each handle two legs. Partners run the entire course together but can divide much of the work at the exercise stations according to their strengths.
Those options make the competition accessible to people who are not ready to attempt the full race alone. Some begin with a partner or relay event and later progress to the individual course.
Atabaki compared HYROX’s rise with the earlier popularity of Tough Mudder and Spartan races. It appeals to people who want a challenge beyond a road race but may not want mud, climbing obstacles or highly technical movements.
Although HYROX was several years old by 2025, Atabaki said its large-scale presence in the United States was relatively recent. After beginning with races in only a few cities, it expanded to seven or eight locations and then started appearing in major markets across the country.
Falls Church offers a smaller test
Functional Fitness has operated since 2011. Before moving to Graham Road, it spent eight years at 350 South Washington Street in Falls Church City and several earlier years at 510 Annandale Road.
The gym recently hosted a free HYROX Personal Fitness Test, a shortened version of the full event intended to introduce newcomers to its structure and physical demands.
Many participants can finish the test in about 20 minutes, while average times are closer to 30 minutes and slower attempts may approach 45 minutes. Results can help athletes decide whether to enter a partner division or attempt a solo race.
Atabaki said the abbreviated test still captures some of the discomfort of a full HYROX because several exercises are performed consecutively.
Simpler movements distinguish HYROX from CrossFit
HYROX shares equipment and movements with CrossFit, including wall balls, burpees, rowers and ski machines. The difference, Atabaki said, is that HYROX is more heavily geared toward endurance athletes and demands less technical skill and coordination.
CrossFit competition can require advanced lifting ability, strength, cardiovascular fitness and proficiency in complex movements. HYROX focuses more narrowly on running, basic resistance work and the mental resolve to continue while fatigued.
Atabaki said that simplicity may reduce some risks associated with climbing obstacles or performing highly technical movements under exhaustion, although injuries remain possible in any physical activity.
“In this competition, you’ve just got to push that damn sled,” he said. “It’s just your leg strength and your lungs.”
The format can still accommodate participants with medical limitations. Atabaki said organizers may permit modified movement standards for competitors who are not pursuing a podium finish but want to test themselves.
He recalled seeing an 80-year-old cancer survivor complete an event with a friend while spectators cheered. Some participants pursue fast times, while others enter simply to accomplish something difficult.
Women drive local class participation
Women account for about 95 percent of attendance in Functional Fitness’ three weekly HYROX classes, according to Atabaki.
He believes the combination of endurance, practical strength training and group encouragement has helped build that interest. During interval sled sessions, several classmates may gather around to cheer as one person pushes a sled weighing hundreds of pounds.
The training moves substantial weight without centering on traditional bodybuilding. Atabaki said the gym promotes strength for everyone, particularly women, and that older attitudes discouraging women from developing muscle have largely faded.
The social element also carries into competition. One Functional Fitness client joined three other middle-aged women for a team event, approaching the difficult race as both a serious workout and a shared experience.
For newcomers, Atabaki recommends starting with a local HYROX class or Personal Fitness Test before registering for a full race. Functional Fitness offers a free trial, while additional 2025 competitions were planned for Miami and New York after the Washington event.
