9 EQUIPMENT
Competitors should arrive at races prepared to carry any or all of the following equipment:-
a. Windproof whole body cover.
b. Other body cover appropriate for the weather conditions.
c. Map and compass suitable for navigating the course.
d. Whistle.
e. Emergency food (long races).
These requirements constitute “best practice” and are mandatory at all Category A Long and Medium races.
However any race organiser is free to impose additional safety requirements (e.g. waterproof as distinct from
windproof whole body cover) and competitors must be prepared to accept such requirements as a condition
of race entry.
In the event of settled fine weather, confirmed by a local weather report, the organiser may decide to waive
some of the above requirements for races of other categories.
Organisers must ensure that whatever requirements they specify on the day are met by holding complete or
random checks before and after the start of the race.
Race organisers should be aware of the dangers of hypothermia if injury to runners causes them to stop or
slow to a walking pace. Body heat is lost quickly and in cold, wet or windy weather the onset of hypothermia
can be very rapid unless sufficient warm clothing is carried. This factor should influence decisions on the
extra equipment runners are required to carry in poor or unsettled weather conditions. If necessary the fact
that the weather creates a high risk of hypothermia should be stressed to competitors.

I really cannot see that this needs any review.
a. Is clear - this is a minimum requirement and I think if someone has a jacket without hood that shouldn't be an issue. There is the additional warning that waterproof may be requested and anyone who turns up at a race without waterproof jacket and trousers are risking not being allowed to run to start with and also risking their own well being if they get passed the ROs scrutiny.
b.Covers not just hat and gloves, but sun protection which for me was equally important at Duddon a few years ago when I was out for 6 hours on a super warm day.
It basically means be prepared and we should all do that. We have our different ways of being prepared and so some flexibility has to be given by ROs as to the different efforts that athletes make to be comfortable and safe.

We cannot start getting too prescriptive and officious or where does it all end? Do we stop someone running around a race in trail shoes instead of fell shoes? Do we insist that gaiters are worn?
Do we have to specify what counts as emergency food and how much of it we have to carry?
Do we have to sound check the whistles?

What we have is fine, generally works. If organisers have any event specific requirements like radio or mobi then that will be in the race info to start with and if the regular equipment that we take is deemed insufficient on the day, then probably the race should be cancelled.
