We're going to East Africa to learn. Why are 66 of the world's 100 best marathon runners Kenyan? Why is physical activity normal. How many neck bones does a giraffe have, and what's its blood pressure? We will meet incredible champions, and people suffering in pain. We will take on epic challenges.

Some of us will run Mt Kilimanjaro in a day, others Mt Longonot, but the challenges and rewards will be significant. Some of us will work in local hospitals, and train nurses to treat pain at the end of life - and help get medicines to people in need.  Please give generously or tell the world about this adventure.
