Choose your distance and conquer the course.
Get ready to test your grit at Tough Mudder London South, the classic obstacle course challenge at Holmbush Estate, West Sussex on Saturday 19 and Sunday 20 September 2026. Choose a 5 km course with 12+ muddy obstacles or push yourself on the 15 km route with 20+ brutal challenges through wooded terrain, mud, water, climbs and crawls. Finishers earn the iconic orange headband, medal and finisher tee, and you can soak up the festival‑style Mudder Village afterwards.
Take on the challenge for a cause! Why not run and raise funds for The Elizabeth Foundation, turning every muddy step into support for children with hearing loss — motivate your sponsors and make your effort count.
