Good Morning Britain presenter Charlotte Hawkins will think of Bill Turnbull "every step of the way" as she embarks on a 26.2-mile challenge for Prostate Cancer UK.
Charlotte, 47, will don the charity's blue and black colours as she participates in Run the Month Marathon Edition in a bid to raise awareness and money for the disease, which Bill was diagnosed with in November 2017.
The former BBC Breakfast host, who was an ambassador for the charity and worked with Charlotte on Good Morning Britain and Classic FM, died at his Suffolk home on August 31 this year at the age of 66.
