A lean, 6ft, 45-year-old mountaineer and entrepreneur, Tim is a strong looking man. He will have to be. Next summer he and his project partner, former UK squad kayaker Geoff Shacklock-Evans, plan to spend several weeks on an iceberg being towed by a kite. The daily routine will involve securing anchor points, handling a revolutionary kite system, taking complex measurements, and staying very alert. Crevasses, seasickness and sub-zero winds will feature.
