Ferne McCann, her mum Gilly McCann and her new boyfriend Lorri Haines took on the gruelling Great Manchester Run on Sunday (May 22).
The reality star, 31, was cheered on by the crowd as she crossed the line after clocking an epic 60 minutes on the 10k run.
Ferne later admitted to her 2.8 million followers on Instagram that running was not her sport and even putting her trainers on was "tough".
But despite her early grievances she explained how nothing will ever come close to the "sense of accomplishment" and "endorphin rush" she experienced as she crossed the finish line.
The 31 year old wore a grey sports bra, which revealed her incredible figure, as well as black leggings and white running trainers.
The TOWIE star even bumped into some legends of the sport, including; Olympic gold medallist Dame Jessica Ennis-Hill and Olympic gold medallist Paula Radcliffe MBE.
She also grabbed a selfie with BBC Sport presenter Gabby Logan.
Meeting her heroes made her achievement just that little bit more special as she even admitted to growing up watching athletics because of her mum.
Taking to Instagram to post a series of photos from her day, she wrote: "Wow to the @great_run you lot KNOW how to throw an epic RUN.
"Ok guys today was pretty epic. Sport is something I’ve always loved growing up. I’ve grown up with the athletics on our TV because of my Mamma.
"So to meet some sporting legends today was pretty special. But running….running is not my sport. However the @great_run team wanted me and my family to get involved with the Great Manchester Run.
"And ok we didn’t do the half marathon but I challenged myself to the 10k. And smashed it in 60 minutes.
"I’ve never been a runner but started because of this run & I’m so glad I did! Don’t get me wrong it was tough to stick on my running trainers and start.
"But NOTHING can come close to the endorphin rush I felt at the end. What a sense of accomplishment and I’m so pleased I got to experience it with my incredible Mamma @gillymccann & boyfriend @lozzahaines."
Ferne paid tribute to the people of Manchester as the run coincided with the five year anniversary of the dreadful Manchester Arena bombings that killed 23 people.
She posted: "The joy of manny was very much felt! And we are so grateful to the crowd who cheered us to push on.
"I’m in awe of the people of Manchester at the date 5 years on to the Manchester Arena Bombings, of your spirit and encouragement.
"My strength, love and prayers go out to the people who were and still are affected by that time."
Ferne also included a special thanks to her sister for looking after her four year old daughter Sunday.
She added: "Ps. Thanks to my sis and bro in law for taking care of Sunday this weekend we love you. Was a little star struck meeting @jessicaennishill & @paula_radcliffe too."
Things are moving fast with Ferne and new partner Lorri – and not just when they're running together.
On Wednesday's (May 18) episode of First Time Mum the pair decided to throw an incredible peacock-themed party in celebration of their love with all of their closest friends.
Before the do was over Ferne decided to ask Lorri a big question.
Ferne said: "Look, I just feel like this is so right. I love you, Mr Peacock. I know this is really weird but you and Sunday are getting on swimmingly, my mum loves you.
"You living in Chelsea, is such a long way and I know that your lease is up on your flat. I just don't want to waste time."
With a smiling Lorri asking: "What you saying?" to which Ferne replies: "Like I want you to be around more and I've never felt so sure and this isn't a hasty decision. But I want to live with you…"
Lorri was left delighted as he exclaimed: "Like deep down, that's all I've ever wanted" with Ferne replying: "Shall we do it? I want to live with you!"
With Lorri responding: 'I want to live with you, yes, let's do it!"
