As thousands take to the streets of London and pound the pavement for their chosen charities, we want to hear about your experiences.
This year’s London Marathon takes place on Saturday and the 26 miles run around the river Thames is the 35th in its history.
Idris Mansoor is just one of dozens from Dewsbury who will lace up their running shoes for the event this weekend.
Mr Mansoor is raising money for charity VICTA, which helps visually-impaired children and their families.
He is running the race for the second time.
An event last month at Dewsbury Sports Centre raised £1,000 for the charity.
Around 30 members of the centre cycled non-stop for three hours to raise the cash.
If you are running in the race this weekend, get in touch with us and share your gut-busting experiences.
We want to see your pictures, videos and stories.
