The Norseman Xtreme Triathlon in Norway begins with a 3.8 km swim into a fjord from a ferry, a 180 km bike with about 3,000 m of climbing, and a marathon finishing atop Gaustatoppen at 1,880 m, with only the top finishers earning the coveted black T-shirt.
Entry runs about NOK 5,000 (around $475), with a lottery for the roughly 300 slots. It earns Best Value because few events deliver this iconic a challenge at a standard race price.
