HEIGHTENED HEART RATE
Symptoms: Your resting pulse is higher than normal over a period of days. Solutions: “I’ve experienced this symptom of over-reaching,” says Dr Murray. “I was running John O’Groats to the Sahara, 34 miles a day. I knew that this was a symptom and couldn’t do much about the volume, but I made sure I was optimising rest and refuelling properly.” It’s useful to know your average resting HR – using digital monitors or a logbook – and taking it at consistent, restful times of the day.
