With more skin on show we triathletes are particularly vulnerable to insect bites.
But a few simple measures can reduce the chances of being eaten alive while you train.
Insect repellent sprays and roll- ons offer patchy coverage so experts advise rubbing repellent into your skin once you’ve applied it.
If you can’t stand the smell of DEET, try Avon’s Skin So Soft Fast Hydration Dry Oil. It’s not marketed as a repellent, but outdoor workers in Scotland and even the Royal Marines swear by it for deterring midges, thanks to its subtle citronella properties. If you do succumb, soothe stings and itches with miracle-working Eurax cream (£5.49; Superdrug).
