How to prevent heat exhaustion and heatstroke when you are out with your dog this summer

In the past two years, the Briton has travelled around the world to compete in half Ironmans – a long-distance triathlon also known as the Ironman 70.3. When in Hong Kong – the city she’s called home for more than 20 years, and where she runs her own creative agency – Holyoak loves to hike and wakeboard with her kids.

“I have a routine if I’m hiking or racing – loads of pre- and post-workout fluids, including electrolytes, and avoiding alcohol and caffeine. I’ve had friends hit the trails in the midday heat after a night out drinking, fuelled by morning coffees, and they have suffered. Prevention is always the best strategy.”

As more people head for the hills this year, many having been in self-imposed isolation at home because of the coronavirus pandemic, there are fears of a spike in heat-related illnesses.
