"The current advice is to drink only when you feel thirsty, because the body acts like a sophisticated sensory device and you'll get a dry mouth and feel dehydrated when you need to drink.

A more common complaint among runners than fainting is the impact on joints, says Mr Dixon, although the risks should not be exaggerated.

"It's a high-impact activity but the more you do it, the stronger your joints get. There's a fallacy that it wrecks your knees and ankles but there's a long-term study that says the more you do it, it ends up strengthening them."

Dull pain

The so-called Big Five complaints are shin splints (sore shins), runner's knee (also called patellofemoral pain or PFP), plantar fasciitis (foot irritation), iliotibial band syndrome (thigh irritation) and Achilles tendinitis (lower leg irritation), he says.

"These are generally wear-and-tear injuries," says Mr Dixon, who says he has never experienced any of them himself.
