When I was training for my half marathon, I found it quite tricky to eat the right things and the right amounts before my longer runs to ensure that I had enough energy but wasn’t too full. It can be so hard to know what to eat when training for a race and it is important to get it right as what you eat can considerably affect your performance. Some days I ate too much and suffered with a sore tummy and a stitch en route – the absolute worst feeling when you’ve still got 7 miles to go! Other days, I hadn’t eaten enough and simply ran out of energy a few miles into my run. So what should you be eating and how much?
