Infinity: 8 Hours of unlimited laps
Infinity is eight hours of endurance, determination, frustrating penalties, tactical 5K & 15K lap building and your shot at achieving Elite or Contender status at World’s Toughest Mudder.
Infinity at Belvoir Castle is an experience that defies time, logic, and your perception of what your legs can handle. You’ll hit moments of clarity, moments of disbelief, and moments where you become deeply suspicious of every hill you see.
15K (20 obstacles):
15K with 20 obstacles that test fears from heights to freezing temperatures to tight spaces. The obstacles are relentless and the satisfaction at the finish line is elite.
Finish it, and you’re over halfway to earning your 2027 Trifecta Medal, your personal trophy proving you willingly subjected yourself to mud, suffering, and several minutes of questioning every life choice that led you here.
5K (12+ obstacles) :
Don’t be fooled, the 5K hits fast and hits hard, you’ll be ankle-deep in filth before you’ve even found your pace, sliding into the mud like it’s chasing rent and losing your dignity at obstacle three. Meanwhile your ego has ghosted you and your Garmin is drafting a resignation letter.
Bonus: finishing the 5K at Tough Mudder Midlands earns you step one toward the brand new Tough Mudder Trifecta. Complete a 5K, a 15K, and an Infinity in 2027 (anywhere on the globe), and you unlock the Trifecta Medal, your year-long badge of mud, bragging rights, and Instagram content that will make your friends weep with envy.
THE VIBE: BELVOIR CASTLE RUNS WILD

Tough Mudder Midlands has a reputation for a reason. This is the event people talk about for months, the one with scenery so beautiful yet incredibly challenging at the same time. Don’t be the “maybe next year” person, be the “I conquered a castle” person.
