Thanks. Bra choice is entirely limited by restraint properties - 32J and cotton bras just don't mix! Will play with the plaits to try and get the technique sorted in time - keep thinking about Triathlon but am terrified of cycling on the roads!
I rub my hair with coconut oil and braid it beforehand. Wear capris under running shorts, no pants. Non cotton sports bra under UV swim shirt to keep the sun off and that it dries quick. Do not wear anything cotton!
If its the riding on the road in a race you don't like the thought of, then there are a few tris with closed roads or circuits. The Dorney lake ones are very good as the lake is shallow, warm and easy to navigate in, and the bike course is one side of the lake, run the other. Makes it super fast too!
Rat Race is the Burleigh House one! Wonder what I'm letting myself in for!
Also while it is comfy to go commando under running leggings/capris, I second the running shorts over the top since (a) they are seldom as opaque as you think and (b) leggings do split, particularly on certain obstacles if you're unlucky.
