It's that time again. The London Marathon is taking place today, and various brave celebrities are taking part for charity.
Scores of famous faces will be taking part in the gruelling 26.2 mile run through London in a bid to raise money for different charities - or just prove to themselves they've got what it takes to finish.
Marathon regulars Chris Evans, Kirsty Gallacher and many EastEnders stars are among the many to be posting on Instagram to share their excitement and fears.
The Great British Bake Off's Candice Brown, who is among the many, shared a touching message as she does the run in memory of her late grandfather.

I'm somehow more nervous for it this time round - my own type 1 Diabetes has not been playing ball marvellously during the training, which has made things trickier, but I'm still determined to run strong and true."
