“When you run and your hips are tight… you actually create more stress with each foot strike into your Achilles,” she explains. And if you don’t have great hip or pelvic stability, your foot and ankle have to work overtime to compensate.

That makes a lot of sense. We’ve spoken about referred pain before – specifically when it comes to running – about how painful knees are often more a result of weak glutes than dodgy cartilage. But a few months ago, I went to see a physio for a general running MOT who got me down on the ground to do a series of hip and pelvis strengthening exercises, including kneeling side planks (touching bum to the floor), clamshells and hip thrusts.

Despite doing a fair bit of balancing, the odd spot of yoga and some strength training, I was in agony by the fifth rep of each exercise… suggesting that perhaps I wasn’t as strong and stable in the hips as I thought.
