On 9 May 2003, armed robbers broke into Tim Challen’s rented accommodation in Nairobi, Kenya. They shot him just below the left knee - the bullet exploding in the leg and shattering the Fibula and Tibia bones before embedding itself in the calf muscle. After surgical operations in Nairobi, Challen was flown back home to Geneva, Switzerland, where he underwent further interventions. In December 2003, pins were finally removed from his leg - followed by a long period of rehabilitation. On 28 February 2006, having founded the Kilimanjaro Initiative, Challen and youth from Kenya and Tanzania reached the summit of Africa.
