Ultra X Tanzania is a multi-stage ultra marathon that takes place over five days in the stunning scenic and seldom travelled backcountry of northern Tanzania around Mount Kilimanjaro. The route showcases the best of Tanzania and the best of Africa.
The event welcomes a very international field. In 2025, we had participants from the following countries – South Africa, Germany, France, Australia, Portugal, UK, Hungary, France, NZ, Spain, Ireland, USA, Sweden, Denmark, Austria, Netherlands, Venezuela, Rwanda and Switzerland!
Competitors can expect to climb up part way the bucket list mountain Kilimanjaro, the tallest free-standing mountain in the world, whilst also covering savannah, forest and running or walking around lakes filled with wildlife.
During this unforgettable week, competitors will experience the place, the people, and the beauty of this iconic country in full.
Ultra X welcomes runners and walkers and everyone in between. The majority of people who take part in this event will walk half the course.
