This unique extreme cross country run is at Longleys Farm, Hailsham, East Sussex.
With a whole host of natural obstacles including crawling through bog, ditch jumping, fallen trees, ponds, and field running, this mud run in the open and wild Pevensey Levels countryside is like no other! The next Mad Marsh Run event takes place in 2023. The 5k and 10k runs take place on the same day.
