Jamie Laing threw up during day four of his brutal Ultra Marathons challenge on Thursday where he was comforted by his wife Sophie Habboo.
The BBC Radio 1 presenter, 36, who admitted his 'body is totally broken', has now reached an incredible £500,000 in donations for Comic Relief.
The milestone amount means that Greg James will be joining him for a run on Friday, wearing in a wedding dress.
Jamie's penultimate route saw him run from Kegworth, through Belper and Derby, before finishing in Matlock.
Speaking after completing his third day on Wednesday evening, he said: 'That was the hardest thing I’ve ever done in my life, hands down.
'There was a point today where we were about halfway, 25 kilometres, in and I just didn't think I had it. That was it. I was done.'
He continued: 'But it was amazing to run into the crowd at Loughborough, it was incredible – and for Oli and Soph to surprise me today, I couldn’t believe it.
'Everything is quite overwhelming at the moment - I’m a broken man right now and although my body is seizing up and I’m mentally drained and scared about tomorrow, somehow it is still a good feeling. We go again!'
It was revealed by Matt on Thursday morning that this total donations had been topped, reaching a whopping £510,000 and sending Jamie into tears.
Jamie will be joined by friend and former Made In Chelsea co-star JP (Josh Patterson), who will provide some much-needed moral support along the way for his final run.
The money raised for Radio 1's Ultra Marathon Man with Jamie for Red Nose Day will provide vital funds that could help put food on plates and roofs over heads, keep little ones safe and help support families affected by conflict here in the UK and around the world.
Jamie has set expectations high after completing day one of the ultra marathon in an impressive 5hours and 44minutes and burned over 4,000 calories.
Overcome with emotion after finishing day three, Jamie embraced his friend Proudlock.
Speaking to Jamie, Proudlock said: 'You've got this. I'm so proud of you, mate. It's a rare sight to see you cry.'
He added: 'You've got me, I mean I cry a lot - seeing that video earlier of you two when you started welling up, I was crying on the train up here.
'Dude I can tell how hard it is, but you're doing it mate, you're crushing it.
'There have been so many times over the last fifteen years where I've been so proud of you and this right here is number one. I've never been prouder. Never.'
Radio 1's Ultra Marathon Man with Jamie Laing for Red Nose Day will be broadcast live on Radio 1 and BBC Sounds across the week, with video highlights on Radio 1’s social channels.
