14 degrees apparently, although most events may make it compulsory even above this

or at least make you sign a wetsuit exemption one.

Probably best to wear one as it'll be f**kern taters without one, plus you get the extra buoyancy.

You can hire one from Tri Harder in Dereham if you don't want to splash out on one for just one event.
