The concept of sisterhood refers to a bond of solidarity and support among women.
And Team GB are not short on the number of sisters - literal and metaphorical - that have inspired each other on the Olympic circuit.
From the deepest depths of sibling rivalry to motivating each other to achieve their dreams, sisterhood can be tested to the max or soar to new heights in sport.
This International Women's Day, we hear from two pairs of siblings that define the value of sisterhood in sport.
Zoe and Izzy Atkin
Izzy and Zoe Atkin have become a history making sister duo in recent years.
At PyeongChang 2018, Izzy won Britain's first ever Olympic medal on skis with freeski slopestyle bronze.
Cut to four years later and she made her second Olympic team - and this time, she wasn't the only Atkin in the squad.
She was joined on the ground at Beijing 2022 by her younger sister Zoe, who competes in the freeski halfpipe discipline.
Although the sisters travelled together to Beijing, Izzy's competition was sadly cut short, withdrawing from the slopestyle and big air competitions due to a pelvis injury that had not fully healed. Zoe finished ninth in her event.
Classic sister mentality
Izzy has since retired from competitive skiing but still enjoys watching on from afar as her little sister continues her own sporting journey, winning world bronze in 2021 and silver in 2023.
The two are very close, still tearing up the slopes together when they can and putting their sibling skiing rivalry on the backburner - to some extent.
"It’s inspiring and so amazing to see Zoe really excel in the past few years" Izzy said. "I know how hard she’s worked and it’s so rewarding to watch it all pay off.
"We’ve always been supportive of each other no matter which area of life. It also probably helps that we picked different skiing disciplines.
"I love skiing with Zoe. She’s my sister and my best friend and whenever we’re skiing together it just feels fun and natural.
"I’ve never felt as though we compete against each other, and I think she’d say the same thing."
Cue the younger sister completely derailing that beautiful sentiment: "I did everything she did and anything that she did, I had to do first and better! Classic sister mentality."
Inspiring a career
All sibling rivalry jokes aside, Zoe admitted that it is was ultimately her older sister who helped pave the path she now skis.
Having never initially dreamed of going to an Olympics until her sister soared to historic heights, Zoe suddenly saw a whole new world of possibility open up in front of her and ultimately thanks her sibling for turning her eyes to it.
And as he now aims to make her second Olympic team at Milano Cortina, Zoe can't wait to make her own destiny.
"Izzy is four-and-a-half years older than me, so I was never as good as she was when we were still competing together," she said.
"It was really inspiring for me to watch her as she set the bar of what was possible for me.
"I never thought 'I want to go to the Olympics' or medal until she did it.
"Seeing her do it really opened the doors for me and I'm really grateful to her for that. I wouldn't be at the level I'm at now without seeing her do that so I owe my whole career to her."
Makayla and Leonie Gerken Schofield
The Gerken Schofield name has become a staple of British mogul skiing in recent years.
Sisters Leonie and Makayla both took up the sport as children, alongside Leonie's twin brother Thomas, and went on to make their Olympic debuts together at Beijing 2022.
It was a performance that saw Makayla claim Team GB’s best-ever moguls finish at a Winter Olympics with eighth place.
The two sisters have since taken different paths as Leonie stepped away from the slopes in September 2023 and Makayla continues to rip up the World Cup circuit.
Having your sister's back
Unlike the Atkin sisters, the Gerken Schofield clan all competed in the same event, which meant that sibling rivalry came down to the finish line at every World Cup and major championships.
But Leonie knew that whatever the result, she would always have a someone to turn to.
"Competing against my little sister was always hard, especially in duals as it’s a knockout," she said.
"Whoever won felt sorry for whoever lost, but having my sister by my side while competing helped me so much during my career.
"Especially when I was having bad days she knew exactly how to pick me up and vice versa. I knew I had a shoulder to lean on and someone to speak to."
It's a thought that was shared with Makayla, who said: "I am beyond grateful to have had my siblings support, I always had someone to go to and a shoulder to lean on when needed," she said.
Never giving up
Leonie recorded her first World Cup top 10 finish in 2020 but was plagued by injuries throughout her career, resulting in two knee operations, three shoulder dislocations, a broken collarbone and a herniated disc.
But no matter how they compared on the slopes, it will always be Leonie's unwavering determination to get back up from a fall that lives on in Makayla's mind. Inspired by her sister at every turn.
"We started competitions together at a pretty young age, my sister was always better than me and a part of me was somewhat jealous of that but I always wondered if I did beat her how would it make me feel," she said.
"Our journeys were very different, we both went through some very rough times both mentally and physically.
"Leonie suffered many injuries and every single time she fought her way back to be able to compete again.
"This is why she will always be my biggest inspiration, she taught me what never giving up truly means."
Leonie added: "Going to the Olympics together felt unbelievable. Seeing Kayla achieve her best result in 2022 at the Games was amazing. I miss competing by her side."
