P.s. please, create label long-distance-running. Running is a bit vague here, this is quite different thing -- more about endurance running and sometimes related to other activity such as trekking. But the common element to carry first-aid-kit is long-distance and unknown places so you need to be better prepared than locally.
Should the running tag be broken up? What are the arguments for or against it?
EDIT: Dave's answer makes sense here. Retag things as necessary as they come up. No need to plan out everything right now.
