What if your next competition felt less like a workout and more like a night out?
Where the beat drops between rounds, the lighting pulses with your effort, and your next personal best happens to a live DJ set?

METRIX is not just another fitness event. It is the beginning of a new cultural moment—where nightlife energy meets elite athletic performance, and training becomes a full-sensory experience. Created by former Royal Marine turned celebrity personal trainer Will McLaren and entrepreneur Toby Spooner, METRIX is redefining how and where we compete.
Now, after a sold-out debut in London, METRIX returns with two major UK events—and BOXROX readers get 20 percent off with the code BOXROX20.
The Future of Fitness Starts Here
METRIX combines structured athletic competition with the production value of a music festival. You and your teammate will compete across five stations in a you go I go format, racking up as many reps and meters as possible while world-class DJs power the entire experience with live sets.

Forget bland lighting and silent reps this is high performance in high energy spaces, designed to push you physically while immersing you in sound and community.
What to Expect
The METRIX format features:
- Ski Erg
- Burpees Over a Line
- Row Erg
- Assault Bike
- Shuttle Runs
Each station runs for 10 minutes, followed by a 4 minute rest. From the moment the music starts to the final buzzer, you are in a training environment unlike anything else.
More Than a Competition
This is not just about competing. METRIX is a full day fitness experience, complete with recovery lounges, refuel stations, and brand showcases from ON, Red Bull, Exalt and more. Whether you are on the floor or in the crowd, the entire space is designed to keep you engaged, inspired, and moving.

Where and When
Following its first sell-out event, METRIX returns to two of the UK’s most iconic venues:
- Manchester – 2 August 2025 at Depot Mayfield
- London – 28 September 2025 at Magazine London

From lighting and sound to scale and crowd energy, these locations bring the vision of METRIX to life.
