How many of you remember to put sunscreen on when you go for a run? If you're going to run 69 miles, you had better remember it.
Julie Nisbet, a 34-year-old mother from England, is an ultramarathon runner. At a recent event, she forgot to reapply sunscreen, and developed debilitating sunburn.
Nisbet's legs are not a pretty sight. You can read the details below, courtesy of the Daily Mail.
Mum-of-two Julie Nisbet, 34, was running from coast to coast along Hadrian's Wall between Carlisle and Newcastle for an ultra-run called 'The Wall'.
But after completing the 21-hour mega-marathon on Saturday last week, Julie noticed small sacs of pus bubbling up across her red-raw calves.
After 'screeching in pain' and covering the blisters in bandages, she went to hospital - but the 'gruesome' blobs only grew larger.
'I was wearing sun cream at the start of the race but hadn't reapplied - sweat and water had pretty much got rid of what I had on the backs of my legs,' she added, explaining the temperature at its hottest was about 30 degrees Celsius.
Nisbet underwent a bunch of treatments and procedures, and seems to be recovering nicely, considering the circumstances.
Bet she remembers the sunscreen next time.
