broke down in tears as he was reunited with his loved ones after admitting he was feeling 'rotten' on the seventh day of his gruelling bike challenge.
The Radio 1 Breakfast DJ, 40, is cycling 1000km in eight days on a tandem bicycle, and has been surprised by family and friends along the way, including earlier this week.
As Greg prepared to start the next day of his trek, which would take him up to the Scottish border, he confessed he was starting to feel its impact.
The presenter broke down as he embraced his sister and niece who had joined him for the latest leg of the challenge on Thursday.
Earlier this week Greg revealed he's been 'masking his emotions' after sharing his father Alan had a stroke just days before he was due to start his bike ride, meaning his parents were unable to join him.
But with the help of pal , Greg completed the latest leg of the ride, and learned by the end of the day his fundraising total had reached £2.4 million.

Speaking on the Radio 1 Breakfast Show, Greg shared that it was the support of his family and his wife Bella that was helping him through the bike challenge.
He said: 'I wanted to let everyone in a bit on what my village is, what the thing is that gets me through, and that's and that's Bella, and that is, that's my lovely amazing dog.
'And that's my Mum and Dad, and that's my sister, and that's my niece and my nephew and all my best friends, and everyone at Radio 1.
'And it's all the people that support me every single day. And it's the breakfast team, they sent me a selfie this morning and I started crying because I saw them in the studio and I was like ''I miss those guys'' because we pick each other up every day.
'So that's that's my village, and I'm lucky, I'm so lucky to have that. I'm so lucky to have those people, and they, and that's why I've been smiling on that bike, even though I've not wanted to do it, because I've had all those people in my head that really look after me when I need it.
'And there are lots of people that don't have those people when they need it, and I feel terrible about that.
'So that's why I wanted to do this, and that's why I'm going to complete it.
'But I am feeling rotten today. But we can, we can go again.'

As Greg continued his mammoth journey north, by the end of the day he was just 75 miles from his final destination of Edinburgh, setting the stage for the last leg during the Comic Relief telethon on Friday.
With donations pouring in throughout the week, the radio star was thrilled when he learned his total raised so far had reached £2,413,981.
While Greg has been supported by many of his famous pals and loved ones on the trek, Jamie Laing caused quite the scene when he joined him on the tandem on Thursday.
Greg supported him on his endurance challenge back then where he wore a wedding dress to run alongside him, and this week Jamie, 37, repaid the favour - albeit in a slightly more racy outfit.
He hopped on the back of the tandem bike in the skimpy outfit, before filming some hilarious dancing videos together for socials.
Greg had previously told Jamie that he'd join him in his challenge in a wedding gown if donations exceeded £450,000, with fans smashing that total with ease.
The wedding dress was also in honour of Greg's now wife Bella who proposed to him ahead of his own Gregathlon challenge for Sport Relief back in 2018.
At the time Greg said of joining Jamie in the dress: 'The whole thing feels like a fever dream.
'I'm currently running with him, at his pace, which I've got to say is really amazing. Genuinely. For running nerds he's doing 6:00/km, still. Day 5.
'I'm with the couple of guys here that he's running with, proper long-distance runners looking after him on the road. And they've said they've not seen anything like it, for a non-runner to immediately fall into that sort of speed is crazy. He's just... he's on one!'
Speaking after his tandem escapade on Thursday Jamie said: 'It was funny and inspiring. Greg is doing such a great job. He's a beacon that is doing it all, and I'm sure would agree it's the team behind him, the radio 1 listeners and public who are the real superheroes because they are the ones donating to raise this incredible amount of money.
'The whole thing was awesome in every way. I loved every second of it, and I loved being in lingerie. I might wear it again!'

Greg added: 'He looked fantastic. Although it took some time to get used to! Fair play for turning up and dressing up like that. It put a real smile on my face in what has been a really tough day in the saddle.'
Just one week before he was due to start his mammoth challenge, Greg's father Alan suffered a stroke during a planned heart operation.
And as he completed day two of his cycle, Greg shared that he became emotional as he neared the finish line as he thought about his beloved father 'big Al'.
He said: 'I feel elated. I feel a bit overwhelmed by all these people who just turned up out of nowhere. I just burst into tears as I was going up to Blaenavon. It was all a bit much. And then I think Sam and Danny were playing Aperture, and it just got a bit much for me.
'Just thought about... I just thought about everything. Just thought about my dad, thought about my mum. It got way too much. It's so silly. It must have been the altitude.'
