Climbathon Kinabalu Park

The Mount Kinabalu International Climbathon is an annual event held in September/October. Started in 1984 as an internal competition to improve rescue efforts on the mountain, it has helped enhance the development of Kinabalu Park's Rapid Reaction Rescue Squad.

In 1987, outsiders were allowed to compete. From a national race, the Climbathon became an international challenge in 1988. It is now acclaimed as the toughest mountain race in the world. The route is gruelling, involving a distance of 21 kilometres and an ascent of 2,250 metres with a qualifying time of 4 hours.

Ian Holmes of Great Britain holds the current men's record of 2 hours 42 minutes and 7 seconds. The women's record of 3 hours 18 minutes and 36 seconds was set by Malaysia's Hasny Salagan.

In 1997 the women's route was shortened. Angela Mudge of Scotland holds the new route record of 1 hour 58 minutes and 23 seconds set in 1999. The women's race will however revert to the full distance this year.

By the year 2012, the Mount Kinabalu International Climbathon format has changed with the introduction of several new routes.
