Mark Beaumont

The clock reads 6:04 a.m. in Shrewsbury, and the air carries that bite of early morning mist that usually signals a day of reckoning. This isn't just a casual spin. I’m staring down the Marcher Castles Way, a 290-kilometer monster of a route that carves through the rugged borderlands of England and Wales. With 5,500 meters of vertical ascent on the menu, I’m not just testing my legs; I’m testing whether my head can handle 15 hours of absolute solitude and suffering. The Fastest Known Time stands at 18 hours and 54 minutes. I’m not just looking to finish; I’m looking to shatter that mark. The mountains don't ask for much, just everything you’ve got, and today, I’m prepared to hand it over. The Frontier of the Marches Rolling out of Shrewsbury, the history of this land hits you before the gradient does. The Marches have been a wild frontier since the 11th century, a place where England and Wales blurred into a landscape of constant conflict and fortification. It boasts the densest concentration of 1,000-year-old castles in Britain, and as you ride, you feel that ancient isolation. To the east, you see the postcard-perfect red brick cottages, but as you bank toward the Welsh border, the terrain shifts into something altogether more rugged. I’m riding the Orbea Terra, a choice born of necessity over aesthetics. While the Terra Race looks faster standing still, 15 hours in the saddle demands compliance and a more relaxed front-end geometry. My setup is lean: internal storage packed with tubes and a mini pump to keep the weight off the saddle, and 45mm tires to soak up the transition from smooth tarmac to broken Roman roads. In a ride this long, your gear has to be an extension of your body, not another obstacle to overcome. Digital Navigators and the Modern Wild There’s a strange irony in using cutting-edge tech to navigate a route that feels prehistoric. Without a Wahoo Elemnt Roam, a journey like this would be a logistical nightmare. In the past, tackling 290 kilometers of intricate bridal ways and forgotten cattle paths meant stopping every ten minutes to check a paper map. You’d lose hours just trying to find the trail. Now, GPS head units have unlocked the ability to ride deep into the wilderness with the confidence of a local. You see a junction, follow the blue line, and keep the hammer down. It’s a total game-changer for ultra-endurance efforts, allowing us to focus entirely on the physical output rather than the direction of travel. The Clee Hills and the Mordor Shift The honeymoon period ended abruptly at the Clee Hills. Up until then, I’d been soaking in the picturesque views of the Iron Bridge, the supposed birthplace of modern industry. But the Clee Hills are the "evil villain henchmen" of this route. The mist thickened, the visibility vanished, and suddenly I wasn't in the Shire anymore. I was in Mordor. The climb was a savage, soul-crushing grind that left me grumpy and gasping for caffeine. It’s in these moments that the mental game starts to fray. You look at the stats—102 kilometers in, average speed dropping—and you realize the easy miles are officially behind you. Fueling the Machine with Precision By the time I hit the Welsh borderlands near Ludlow and Clun, I was deep into my 450th gram of carbohydrates. I’m using Precision Fuel & Hydration gels to keep the engine turning, but after six hours of nothing but syrupy packets, you start to feel like a science experiment. You’re being kept alive in a petri dish of glucose and electrolytes. Yet, the fuel works. Despite the climbing, I hadn't hit the wall yet. The route through Mortimer Forest provided a hit of nostalgia—old-school mountain bike trails that forced me to stay sharp. On a gravel bike, these sections are a test of technical finesse. You can’t just plow through; you have to dance over the roots and brambles, even as the fatigue starts to seep into your bones. The Final Gauntlet: Stiperstones and the Long Mynd The climax of the struggle arrived in the form of three massive final climbs. The Stiperstones was a magical high point, offering a panoramic view of the rolling Welsh hills, but by the summit, I was properly screwed. My power reserves were depleting, and every 15% gradient felt like a vertical wall. Then came the Long Mynd. I hadn't ridden this climb in 30 years, and it greeted me with a 25% pitch that forced me to my knees. The descent was even worse—a technical, rocky mess that would be a blast on a mountain bike but was a death trap on 45mm gravel tires after 250 kilometers of riding. I had to swallow my pride and walk. The risk of a crash that late in the game was a price I wasn't willing to pay. Reflections from the Pain Cave I rolled back into Shrewsbury 15 hours, 13 minutes, and 12 seconds after I started. I set the FKT, but the victory felt more like a survival story than a podium finish. In the final twenty kilometers, when my legs had nothing left and I couldn't even manage a climb on gravel, I remembered something Mark Beaumont told me years ago: don't worry about when you finish, just know that you will. That simple truth carried me through the sunset. I didn't beat the dark, but I found peace in the closing kilometers. The Marcher Castles Way is a brutal, beautiful masterpiece. It demands a capable bike and even more capable lungs. It’s the kind of ride that breaks you down until there’s nothing left but the rhythm of the pedals. I may have set the record, but I’m under no illusions—it’s low-hanging fruit for the next person willing to suffer. For now, I’m content to let the mountains have their victory. I found what I was looking for in the struggle, but I won’t be heading back to Mordor anytime soon.
