An ultramarathon is a long distance run spanning over the standard marathon length of 26.2 miles. The most widely used distances are 50, 100 and 150 km. Ultramarathons may also be timed events such as 24, 48 hours or even a week long.
Because of the length of ultramarathon events, runners will have to rely on themselves for hydration and nutrition in between aid stations. Depending on the race, aid stations may be several miles apart. The runners need to carry hydration is the focus of this design project.
The ultra runner is a person who pushes themself to their limits. There is more of a competition within the individual runner as opposed to other racers.
In order to meet their goals they tend to be strict with their training regiment while maintaining a balance between running and the world outside of running.
