For the past week, Lucy, along with a team from her fitness business 'Results With Lucy', has been raising money for the Cystic Fibrosis Trust, by donning her hiking gear and trekking up the highest mountain in Africa.
Their hard efforts saw them reach the summit and Lucy told fans getting to that point was the "hardest" thing she has ever done.
Taking to Instagram on Saturday (24 October), Lucy shared a photo of herself sitting at the top of Kilimanjaro, shortly after completing her climb. That view is pretty in-credible, right?
Still sporting a smile after trekking 19,000 ft, Lucy said alongside her post: "Look at the view!!!!!! We did it! thanks Ellesse for sponsoring our trip & keeping me dry, it was by far the hardest mental and physical challenge I have ever done!
"There was many times we wanted to break down but we pushed through! It has confirmed that once you put your mind to something u can achieve absolutely anything.
"Good luck to anyone taking on Kili your ganna need it!!!! Thank you all for your donations and support for @cftrustuk it really means the world to me & the @resultswithlucy team!! #Kilimanjaro #charitychallenge #determination #stong #fit #Results4cf #resultswithlucy (sic)"
Following her Kilimanjaro challenge, Lucy jetted back from Tanzania and touched down in Essex yesterday. But despite being totally shattered from her time away, Lucy was in good spirits thanks to a surprise arrival from her beau and Olympic medallist Louis.
Louis had sent Lucy a celebratory present to mark her charity climb. And proving he knows just how to put a smile on his girlfriend's face, Louis had chosen to post Lucy's favourite snack, cheese and crackers, along with a personalised cheeseboard to go with it.
Showing off her present, Lucy revealed she was missing her boyfriend. She gushed: "Back from Tanzania this morning... Thanks @louissmith1989 for my cheese & crackers delivery! He deffo knows the way to a girl's heart & yes he bought me the cheeseboard as well haha. A month apart now .. Missing him x."
Due to their busy working schedules, the couple are often forced to spend some time apart, but have been making their long distance romance work since getting together earlier this year.
And proving absence really does make the heart grow fonder, Lucy and Louis couldn't seem any more smitten than they already do.
Back in March, just months into their romance, Louis told Reveal: "I haven't felt like this for a long time, if ever. It's taken me by surprise. Lucy is just so lovely which is rare to find in someone who looks as beautiful as her."
