I doubt that a ghost-writer would do you justice OB1. Within your creative efforts there are some quite serious issues raised.

What is an U14, U16, U18....?
UKA Rule 7 sets out Age Group rules for Track and Field, Road Running, Race Walking and Cross Country.

Fell Running doesn't have any age group rules and has previously worked on the well established precedent of 1/1 of each year in line with the junior champs, but no RO has been obliged to follow this and can create their own age categories and way of calculation.

It also seems that the Bunny Run Relay has been incorrectly permitted as under rule 10 there isn't a way that I can work out that "Age 10" can run a 3.2km leg. Is it 3.2km as it doesn't mention in the calendar?

You mentioned the English Champs. Although there is literature out there that explains that the English Champs are age as of 1/1/13, that isn't specified in terms of the actual races.
I'm sure they are, but shouldn't the champs races be declared as "Age as of 1/1/13" as Stretton has commendably done?

Rivington for example has the junior info embedded in the Senior info.
Rivington Senior race is "Age 16". On the day I assume as it is senior.
What of the junior races, it doesn't say.

I look forward to seeing Team WEKTRAC at Witton. Happy New Year
