Joel Dommett has revealed he woke up in an ambulance after fainting at mile 17 of the 2025 London Marathon on Sunday. 

The comedian, 39, took to Instagram with snaps of alongside paramedics just hours after sharing a glimpse of his hectic schedule ahead of the iconic 26.2 mile run.

Joel revealed that despite the scare he was able to finish the race after being forced to wait a few hours under medical supervision for his pulse to return to normal.

He wrote: ‘Not the race I expected! I fainted at mile 17 – don’t really remember much but I woke up in an ambulance! Thanks to Frankie and Barry for being amazing’. 

‘I really wanted to finish it. After a few hours my pulse was back and I got going again at a very different pace but really got to soak it all in. Proud of myself for finishing’. 

Joel shared shared a snap of himself with his medal as well as a cute snap of baby son Wilder, who’s babygrow had to be updated after the star failed in his hopes of crossing the finish line in three hours.

Joel revealed that despite the scare he was able to finish the race after being forced to wait a few hours under medical supervision for his pulse to return to normal.

It comes after Joel had left supporters floored as he revealed his exhausting schedule and his journey to the finish line actually began 24-hours earlier when he set off from his house in South West London. 

He proceeded to travel to Leeds for a comedy show before driving two and a half hours to Cambridge for the night. 

Joel had a brief six and a half hours sleep – with the ᴀssumption that he slept straight away on arriving in Cambridge – before getting up again at 6:30am on Sunday and leaving his H๏τel at 6:45 to travel to Greenwich roundabout. 

His schedule, written out precisely on a white board and shared on Instagram, doesn’t end there as he then undertook a half an hour warmup run as he made his way to the starting line ahead of the marathon. 

He explained he needed to stick to his three hour time in order for son baby Wilde to be able to get an afternoon nap in the car ride home.

Once home, if all goes to plan, Joel then has an ice bath and a meal scheduled before being picked up at 4:45pm to head to filming.

Joel captioned the eye-popping post: ‘Swipe for some terrible planning and excellent carb loading.’

The schedule was one of several pictures relating to the event, including a snap of Joel’s running gear, which revealed that he is completing the marathon in aid of Brain Tumour Support.

‘We are all cheering you on and will be tracking you from afar.’ 

A fan wrote: ‘For a person who has had major surgery this year to remove parts of her brain tumour thank you Joel behind you all the way!’ 

Referencing Joel’s aim of completing the marathon in under three hours, Ben Sheppard added: ‘Go smash the hell out of it Joel. Sub 3 Baby!!!!’

She joked: ‘Lol i’m saving this for when i start complaining at mile 14.’

He told TCS London Marathon: ‘It was definitely the hardest marathon I’ve done.

‘Really had to dig deep. Lots of shouting to myself. 

‘It probably weighs, I reckon, probably about 8kg, something like that.

‘The hard thing was it [the costume] was just banging against my head the entire time.’

Joel took to Instagram ahead of this year’s race to admit that he’s glad he will not be weighed down by a costume again.
