Imagine doing ten 10k runs, one after another and starting at midnight - that tough task is exactly what Rod Burton did this weekend.
Rod, a 58-year-old art and antiques dealer, was not content with doing the Caistor Sting in the Tail 10k - so he set his own challenge.
Inspired by his sister, who has just been diagnosed with cancer and is dealing with the news very bravely, Rod decided to complete nine 10k runs in the 12 hours leading up to the official Sting in the Tail race at midday on Sunday.
Rod, who is the chairman of Caistor Running Club, said: “It’s just really an illustration that people can do anything they set their mind to.
“It’s just a case of getting on and doing it.”
Rod, along with a small group of friends from around Lincolnshire, donned head torches and hi vis jackets before setting off on their mammoth overnight challenge.
Several people dropped out early on, but Rod powered through and completed the entire 100-kilometre challenge (including 30 hills).
He said: “It went very well, apart from the pain. I got it done.
“I had a very bad lap at lap six, which was about 6am.
“I was walking most of the lap, I was falling asleep walking. It’s very unnerving when you find you’ve wandered onto the grass.
“But when I started running again it woke me up.”
Rod said the final lap was hard but he managed to run the last mile and had a strong finish.
So how did it feel when he crossed the finish line?
Rod said: “I had a bit of a celebration.
“And I thought ‘I’m never doing that again’.”
He added: “Opinion is split 50/50 - people think I’m a little strange or they’re full of admiration.”
Rod would like to thank his partner Susan Peck and The Settlement for their help with coffees and snacks to keep the runners going.
