This past weekend, while thousands of athletes were grinding through 8km of running and eight workout stations inside Olympia London, Gymshark was doing something unexpected directly across the road.

They opened a jacket potato shop.

Not metaphorically. An actual retro sandwich shop called Frank's, taken over for three days, serving free jacket potatoes to every HYROX finisher who walked through the door. Behind the counter: Spud Man, Britain's most beloved market vendor with 4.2 million TikTok followers, and Grime Gran, an 86-year-old East End grandmother who went viral for her love of grime music. Together, probably the most unlikely partnership in fitness brand marketing history.

The insight behind it

The activation was called The Jacket Patch, and it was built around a specific piece of research Gymshark had done into how HYROX athletes actually feel after they finish.

The finding was stark. Over one in three athletes describe feeling pride or euphoria when they cross the line, but say that feeling has nowhere to go. You finish, you post to social, you leave the venue, and you go home. The race is over in roughly 90 minutes. The training took months.

"Crossing that finish line felt kind of anticlimactic. It didn't really hit me until a few days later."

"The journey felt bigger than the finish line itself."

"It was quieter than I thought, more reflective than celebratory."

These were actual quotes from HYROX athletes in Gymshark's research. And the most common post-race celebration? Food. Specifically, comfort food. The kind you'd promised yourself during wall balls.

What they actually did

So Gymshark leaned straight into it. Free jacket potato at the finish. No catch, no upsell on entry, no QR code to scan before you get your spud. You finished HYROX, you walked across the road, you got fed.

Alongside the food, they made available the Conditioning Club Patch Jacket, a performance jacket with velcro panels on the arms designed specifically to hold HYROX race patches. Available at 20% off to finishers on the day, with surprise free jackets gifted throughout the weekend to lucky athletes. The jacket turns every race badge into something wearable and permanent, a physical record of the work done.

Noel Mack, Gymshark's Chief Brand Officer, put it plainly: "Gymshark exists for people who do gym. And people who do gym work hard, really hard. Months of early mornings, sacrificed weekends, showing up when nobody's watching. And then the race is over in roughly 90 minutes. We thought that deserved more than a social post. So, we showed up at the finish line to give those people a moment."

Why it landed

What Gymshark understood here is something most fitness brands get wrong. HYROX is not primarily a performance sport. It is a participation culture. The athletes showing up at Olympia are not chasing prize money or World Championship qualification. They trained for months, they showed up, they suffered through it, and they finished. That is the entire point.

The gap between what that achievement feels like on the inside and what happens externally in the 90 minutes after crossing the line is very real. Gymshark did not try to fix it with a discount code or a brand activation inside the venue. They built a physical space outside it, one that existed entirely for the finisher, not for Gymshark.

The Spud Man and Grime Gran casting was not accidental either. Both are figures who built genuinely devoted followings without any of the usual machinery of influencer culture. Spud Man sells jacket potatoes at a market in Shropshire. Grime Gran is an 86-year-old grandmother from the East End. Neither is polished. Both are beloved. In a sport whose audience runs largely Gen Z, that authenticity matters more than any celebrity placement would have.

The broader push

The Jacket Patch was not a standalone stunt. Earlier in March, Gymshark ran Battle Stations, a free HYROX simulation event open to anyone with no entry fee and no prior experience required. The two activations sit in the same strategic frame: reduce the barriers that stop people from engaging with the sport, and show up for athletes in the moments the sport itself does not.

HYROX grew from 600 competitors in 2018 to over half a million participants globally in 2025. The UK is its biggest market. London events are balloted. That kind of growth creates a natural opportunity for brands who understand the culture rather than just sponsoring the scoreboard.

Gymshark understand the culture. This weekend proved it.
