Organisers of the Salt Pans Ultra - Botswana.  The hardest flat race in the World and a bucket list event.  An adventurers dream and a great excuse to explore Africa's wilderness in a safe and structured setting.  The race offers both a 50kms and 100kms trail ultra in heart of Botswana's Makgadikgadi Salt Pans, the second largest in the World.  It has been described as being as close to running on the Moon as you can manage on Earth.
