With most races cancelled due to coronavirus, ultra runner Carla Molinaro decided to setup her own.
She started at Land’s End on July 16 and is in a race against the clock to beat the world record to reach John O’Groats by Monday evening.
"I wish I could bottle up the pain to show people how much it hurts," she said. "I knew it would be hard, I had no idea it would be this hard. It’s by far exceeded my expectations."
Along the way, she was joined by other runners including current record holder Sharon Gayter.
Running 16 hours a day, she is on course to run the length of the country and aims to beat the women's record of 12 days, 11 hours, six minutes and seven seconds.
It's an 874 mile journey and she has run nearly 73 miles every day. She didn't even take a break to celebrate her 36th birthday.
She said: “I’ve decided this is the worst birthday present anyone can give themselves and if I ever say this is what I’m going to do for a birthday again, someone needs to tell me to go to a spa.”
