Breast cancer survivor to run 405th marathonpublished at 13:51 British Summer Time 21 April
Some people running the streets of London today will be covering the distance for the first time.
Others have done this plenty of times before.
Apryl Hammett, 52, is falls into the latter category. She is running her 405th marathon this weekend, just two months after finishing radiotherapy treatment for breast cancer.
"It was a shock. I was anxious and afraid but I am happy to be back doing what I love," she said.
