You probably have been completed 10km, challenged yourself to half marathon, or even celebrated your glorious Full marathon recently. What now? Maybe it’s time for you to take a step further, the Ultra Marathon. Any figurative distance exceeds 42.195 is an ultra marathon. In Year 2018, Miri-Bungai Beach Ultra (MBBU) would have been the 2nd edition as the World’s First Beach Ultra! Comparing to the previous conventional ultra events which normal set course on road, loops or trail, Miri Beach Ultra (MBU) has 98% route set on the sandy beach! Although the course has near zero elevation but the soft sandy terrain, adverse heat and certain degree of potential hazard you might be facing are worth for a challenge. The entirely new experience definitely brings a surge of excitement among runners.
