One man who knows better than most is a Merrell ambassador Dr. Andrew Murray who has taken on both the Sahara and the Gobi Desert as well as becoming the first person to run in 43 degrees across the Namib desert.

As an athlete, Andrew has won races in some of the hottest places on earth, including the Sahara Desert and the Gobi Desert.  He also became the first to run across the Namib desert (featuring the highest sand dunes worldwide) in the Namibian summer. He is a brand ambassador for Merrell and a consultant in Sport and Exercise at the University of Edinburgh.

1) Acclimatise to the heat if you can.  In the days leading up to the race, try and be outside in the heat of the day, and spend some time in a hot bath, if you are not used to running in hot conditions

2) Be hydrated prior to starting (aiming for clear or straw coloured urine)- and drink cold fluid at aid stations if you are thirsty.  A fluid that has electrolytes and carbohydrates are ideal.

3) If hot conditions are expected, don’t overdress. I wear light coloured (white) loose-fitting clothing (from Merrell).  I will also wear sunscreen, and a buff around my wrist, to wipe excess sweat away.

4) If the conditions are hot, then you are likely to be a little slower.  If it’s super hot, don’t think about personal bests, but embrace the challenge of completing a marathon on a hot day. Running in a pack may stop some direct sunlight, while I also try and run on the shady side of the road if there is one!
