Hannah Otto has ridden up and down Kilimanjaro in a single day, the first woman known to have done it, and pedalled the last 3 km on a broken leg. What the ride involved, who went before her, and the cause she rode for.
Kilimanjaro National Park allows mountain bikes on one route towards the summit: the Kilema rescue track to Horombo, then the Marangu path to Kibo and a carry to the crater rim. What riding it involves, what the park charges, who has done it, and two easier rides for everyone else.
