The Joy of Six is a regular series of articles from the Guardian which focus on unearthing sport's hidden treasures. This week, the focus was on the worlds most unusual and bizarre races, including the world's longest certified race organised by the Sri Chinmoy Marathon Team - the Sri Chinmoy Self-Transcendence 3,100-Mile Race.
The article notes: "The race was founded by noted spiritual leader Sri Chinmoy, who opened the first meditation center in Queens after moving to the US in 1964. Finishers needn’t complete the full 3,100 miles, but that’s hardly the point. The goal is right there in the name: self-transcendence, achieved by pushing yourself beyond your physical limits."
Other races mentioned included the Iron Man ice competition in Arizona, the Man v Horse marathon in Wales and The Big Five marathon in South Africa, where participants have to dodge the big five game animals: lion, elephant, leopard, buffalo and rhino.
