The Four Feather's Ultra Marathon concept is a self-sufficient style race, whereby runners are responsible from start to finish to carry food supplements and energy bars/gels to be able to get from check point to check point across the race course. Meals are provided at key check points along the route and this has been indicated to runners ahead of time to allow them to plan their nutrition needs for the event.
The race course has been designed according to International Trail Running Association standards (ITRA) on a race course designed as a "fast" styled race route. The FFUM is designed for both new and experienced runners looking for routes that are run-able and challenging under hot and difficult conditions in the jungles of Borneo under the hot Borneo sun. Cut off times for the 90k & 50k are very tight and runners will need to ensure they are able to meet the set cut off times below in order to complete the event.
