My youngest son runs marathons because he likes long-distance running and can raise sponsor donations to support charities while promoting public awareness of the work they do. His next one is the Boston marathon.
His most recent London marathon run (April) raised 4,000 pounds for Guide dogs for the Blind. Since then he's done a half-marathon, a one- mile inter-island open sea swim, a triathlon and a mountain night hike. He loves the physical and mental challenge; the side benefit is publicity and fundraising for charities.
