Are you allowed to carry your own water under UKAA Rules for, say, a 10-mile run?
It would seem that it *used* to be (technically) forbidden in previous editions of the regs, but not now. Currently, it seems to say:
RULE 211 REFRESHMENTS (1) In full Marathons and longer races, Promoters must supply drinks to cater for the entire field at a minimum of every 5km throughout the race. (2) In races of 10km and above Promoters must supply drinks at intervals of at least 5km. (3) In races of less than 10km, drinks may be provided by the Promoter. (4) A Promoter must provide additional drink stations on the advice of the Race Medical Officer. (5) A Promoter should provide drinks for the entire field at the finish.
But no mention of being forbidden to carry your own.
Note that under *IAAF* Rules for 2010-11, it *is* forbidden! : "An athlete who collects refreshment from a place other than the refreshment stations renders himself liable to disqualification."
Or can you carry your own bottle provided you pick it up from the first station?!
