According to the FRA:

Licensing policy
The FRA only licenses fell races which are in keeping with the FRA’s “Principles of Fell Running”1
. In
particular, core principles include the following:
1. Unique character. Key words are “fell”, “runners” and “race”! The FRA does not license trail races,
cross-country races, “challenge”-style events or walks.
2. Non-commercialism. Fell running is a non-commercial, low cost sport. Races should be run on a
“break even” basis or to raise a modest amount for a stated good cause. Entry fees are expected to
be priced at levels in line with what is “normal” for the sport, though the FRA recognises that all
races are different and that some races have hidden costs. Guidance is available on request.
3. Self-navigation. The use of electronic aids (such as GPS devices) for navigation is strictly prohibited
in all FRA races. Use of such devices both is contrary to the ethos of the sport and may bring
seriously increased risk in cases of overreliance. ROs must make this principle clear to entrants and
in particular should not provide electronic “GPX files” (or equivalent) of the route.
4. Self-sufficiency. Aid stations are not expected in fell races. Provision of fluids at road crossings on
very dry courses may be acceptable.
