Anyone looking to lose weight who has a Runner's World magazine subscription can find out the importance of mastering food groups.
Even if the aim of your running trips is to drop a few pounds, you still need to fuel your exercise by eating the right food.
In normal diets, carbohydrates are quick to be cut out, but you can't do this if you're running.
"Carbohydrates are the most important energy source for running, especially long-distance running," Shona Wilkinson, nutritionist at the Nutri Centre, told Runner's World magazine.
The best to do is try and eat healthy carbs, such as basmati rice, spelt, quinoa, sweet potatoes, couscous, squash, pasta and fruit and veg, Ms Wilkinson said.
A good training diet cannot just contain carbs though. It has to also consist of 15 to 20 per cent protein and 15 per cent fat, according to Runner's World magazine.
"Most runners and athletes neglect the huge role that both fat and protein play in their diet and because of this they fail to benefit fully from their training," Trevor Bedding told the publication.
The BBC advises adults to ensure they get at least 30 minutes of moderate exercise around five times a week to stay healthy and maintain weight loss.
