Tough Mudder returns to Hopetoun Estate in 2027 (just outside Edinburgh) with a course that’s as scenic as it is savage. You’ll tear through woodland trails, splash along the shores of the Firth of Forth, and grind your way over gentle climbs and descents with obstacle-packed action from start to finish. Whether you’re taking on the 15K or the 5K, or pushing yourself to do Infinity, this is a route that delivers challenge, variety and views for days. Kids by Spartan course also available for age 4-14..
