Race Info
Runners are allowed to have only one designated pacer accompanying them at any given time, with an exception made during the final stretch of the race, as mentioned in #1.
While aid station food is available for consumption, it is essential to refrain from extended stays and excessive consumption of items. It is crucial to consider that several of our aid stations are situated in remote and challenging locations, making it difficult to stock supplies for a large number of runners.
Thus, we kindly request that pacers come well-prepared with their own trail food, gels, and other sustenance and use the aid station snacks and hot food judiciously. Such consideration greatly aids our efforts in efficiently organizing the race.
Anticipate a lengthy and arduous journey, and embrace the challenges ahead, for it is in these trials that the true spirit of adventure flourishes.
