Running 268 wild miles though the UK requires more than just consistent training and mental fortitude, it requires a ton of gear in your one and only drop bag, especially since you are not allowed any crew and this race is a self-supported event requiring athletes to take care of themselves, not just over the 40-60 miles between checkpoints, but also while in a checkpoint. As such, runners must pay special attention to both the gear and the nutrition they pack in their drop bag, This one 20kg (42 lbs) drop bag follws them along on the course, allowing them access whenever they enter one of the five checkpoints over the course of the 268 mile race. This makes the drop bag a serious lifeline for all runners. Mess up the contents of your one drop bag and you may mess up your race.
