== 50K ==

In many ways, the 50K is an odd distance. It is only about 5 miles longer than a marathon, rather than part of the usual doubling that occurs in the progression of '5K-10K-half marathon-marathon-50 miles-100 miles'. Some runners can run a 50K like a marathon - continuous running at an intense pace, where every second counts. For most runners however, this approach does not work, and the 50K needs be treated as an ultramarathon, with varying the intensity, eating, etc.

== Multiday ==

I have not participated in multi day events, so I cannot provide any useful advice. One day I hope to update this section with some personal experience ;}
