A cream cracker to a massive squirrel – the 71 London Marathon record attempts

Seventy-one people are to put their best foot forward in order to break London Marathon Guinness World Records – including DJ Adele Roberts who hopes to run the fastest marathon with an ileostomy, and a ‘cream cracker’ on legs.

BBC Radio 1 weekend Breakfast Show DJ Adele Roberts is hoping to raise awareness during Bowel Cancer Awareness Month, following a surgery to remove her bowel 18 months ago and less than a year after completing chemotherapy.

She is to attempt the Guinness World Record for the fastest marathon with an ileostomy (female), with currently stands at 4:00:00, and to show that you can bounce back after having cancer.

Sally Orange, a 49-year-old from Salisbury, is hoping to use her London Marathon GWR attempt for fastest marathon as a savoury food item (female), while dressed as a cream cracker to show that she is “crackers about mental health”.

The former army major was medically discharged after 22 years of service due to her mental health and hopes that her quirky outfit – which she has worn at her local parkrun on weekends – will help to break the stigma surrounding mental health conditions.
