Thirsty?
From the doctor
Ballito GP and ultra runner Dr Rosie Carey explains how dehydration affects your body and how to avoid it.
The 2013 Comrades up run is etched in my memory. It was unusually hot, with temperatures above 30°C, and a blistering headwind picked up. I started vomiting 45km into the run and the second half of the race became increasingly torturous as I got more and more dehydrated.

Running up Polly Shorts was like an apocalyptic scene, with runners lying collapsed every few metres on the side of the road. The stats say it all: of 14,200 runners who started, just over 10,000 finished and 366 runners ended up in the medical tent
