Clarens Cosmos Challenge 5th Anniversary: A Must-Do Trail Run Event!

Ready for an adventure that will leave you exhilarated and craving more? The Clarens Cosmos Challenge is back for its 5th year, and it's better than ever! This 2-day trail run promises breathtaking landscapes, thrilling terrains, and an unforgettable experience. Whether you're an extreme sports enthusiast or simply seeking a serene escape, this event is calling your name.

Stage 1: Welcome to Old Mill Drift Guest Farm

Distance: 17Km | 11Km

Discover the magic of Old Mill Drift, a historic 1,646-acre guest farm and Warmblood horse stud farm. Located just 27km from Clarens and Fouriesburg in the Free State, South Africa, this gem offers pet-friendly, self-catering accommodation along the Caledon River. The enchanting setting, with its stark seasonal contrasts and stunning landscapes, provides the ultimate thrill for trail runners and a peaceful retreat for those seeking tranquility.

Nestled at the foot of the Maluti Mountains and spanning 14km along the Caledon River, the natural border between South Africa and Lesotho, this exquisite land is the perfect backdrop for a technical trail run.

Route Highlights:

  • Aardonyx Discovery Site: Stand where the new dinosaur species, Aardonyx, was discovered. This 7m-long herbivore is key to understanding the evolution of the Sauropods.
