Running

i'm buying a rapha merino slevless baselayer for the marathon (to go under a proper vest I imagine, no one wants to see me in skin tight anything), haven't had a single bit of chaffage wearing my helly hansen or rapha long sleeve ones on every run.

and I can be prone to chaffage, as anyone who's seen my bloody nips photo can attest.

Micropore tape is a much better solution than extra layers, London has a tendency to through out surprisingly warm days for the marathon.

It's also good for avoiding chaffing from heart rate monitors..
