You've been around long enough Chris. Much longer than me.
Nine Standards - Jan 1st - Course Record 51:44 is a BM so no mandatory kit requirement set by the FRA.
Ingleborough - July 19th - Course Record 44:15 is an AM so mandatory kit of Full Waterproof body cover, map,compass whistle required.
Of the 2 races, I know which as a competitor I would chose to take the full kit to and a little extra and that is Nine Standards.
If the rules are stupid, and illogical, then people will disrespect them.
I'm sure the 9 standards RO will apply the mandatory kit even though not compelled to and that's what makes these rules so stupid.
