“Belvoir” might mean “Beautiful View” in French, but don’t let that lull you into a false sense of security. You’ll start with a deceptively gentle climb through the woods, before bursting out into open pastures, where you might encounter a charming little water feature (or two). From there, it’s straight into the infamous “Hills of Belvoir,” because what’s a Tough Mudder without a proper leg-burning, soul-testing ascent?

At the top, you’ll be rewarded with a stunning view of the castle and pit area (that’s if your eyes aren’t too full of sweat and regret to appreciate it of course). Then, it’s a fast and furious descent to the finish line… before heading straight back out for another lap, obviously. The current elevation sits at a modest 200m per lap, but with 100 days to go, there’s plenty of time to make it worse. Hold tight.
