Mario Roman delivers strong debut at an American classic. Grinding Stone Hard Enduro

Two of Plews Tyres’ top-supported riders lined up at Grinding Stone Hard Enduro in the United States, taking on one of the most unique and demanding races on the calendar.

Plews-supported riders take on Grinding Stone Hard Enduro in the USA

For the first time, Mario Roman raced Grinding Stone Hard Enduro, supported by a small team built around the Hard Enduro Burros. With key backing from sponsors including Plews, the Spaniard made the most of his American debut and quickly showed he could adapt to the race’s dry, dusty, rock-filled terrain.

Roman opened the event with a strong second place in the first race, handling the technical conditions with confidence. Known for his precision and bike control, Mario looked at home on the rocky ground and carried that momentum into the main race.

On race day, he stayed sharp and consistent, eventually crossing the finish line in second place overall, just behind local hard enduro star Trystan Hart.

“Happy with the result, but even more with the experience of racing in such an iconic place. A true paradise for hard enduro lovers,” said Mario.

Matthew Green takes on one of the toughest races of the season

Also representing Plews, Matthew Green continued his US Hard Enduro campaign as part of his pre-season build-up for the World Championship. Grinding Stone marked round three of the series and brought completely different conditions compared to the previous event in the Hawaiian jungle, where Green finished third.

Green put in a solid opening performance to finish fourth in the first race, securing a front-row start for the main event. But as the race wore on, the conditions became brutal.

Mid-race, Green summed it up simply:
“It’s getting brutal out there, it’s getting hot.”

The South African later described it even more directly, calling Grinding Stone the “scariest race I’ve ever done.”

After battling through the punishing conditions, Green finished the main race in 10th place, a result that leaves him fourth overall in the championship standings.

Plews tyres deliver in brutal conditions

Both Roman and Green raced with the Plews EN1 Tough One Extreme on the rear, and by all accounts the tyre delivered exactly what was needed. In loose rock, dry dust, and extreme terrain, both riders had the traction required to stay competitive at one of the toughest races in the US series.

Grinding Stone once again proved why it holds such a strong reputation in hard enduro — brutal, technical, and completely unforgiving. For Plews-supported riders, it was another weekend of valuable results, hard lessons, and top-level racing against some of the best in the business.
