Happily recommend Bluestone Holiday Park as accomodation, especially if anybody's taking family or friends along. A real quality location. Not cheap, but nice.
LCW last year was excellent preparation and really well organised. The LCW swim actually felt like a bigger event than the IMW swim did! And if you don't fancy the full distance ride at that point in your programme, you can always just do the first lap (circa 72 miles I think) and then bimble off to do a bit more of the "interesting" stuff around Saundersfoot and Wiseman's Bridge.
The IMW run was horrible. Good idea to do plenty of hill work, because there are no flat, straight bits
. At all
