The line between athletics and bobsleigh is becoming pretty hard to distinguish lately.
Where you would think there are a load of differences between the two sports - and there is - there is also the most unexpected pathway between them that has formed.
With speed and power both determining factors, the number of track and field athletes who have made the switch to bobsleigh over the years is ever growing.
It means that sleds are being pushed by elite level sprinters, flying down the track at breakneck speeds that even Usain Bolt's 100m record could not touch.
It's a pipeline that has seen several British Olympians make the change from summer to winter during their careers, including current pilot Adele Nicoll.
Nicoll took up the winter sport in 2022 when she was already a prolific shot putter, having multiple Welsh and UK titles to her name as well as competing for Team Wales at the 2022 Birmingham Commonwealth Games.
And after helping Team GB finish 17th in the two-women bobsled at Beijing 2022 as a reserve, she's ready to take on the new mantle of pilot at Milano Cortina 2026.
"I feel like I've got a lot of unfinished business from Beijing and I'm in a completely different role now," she said.
"I used to be a break woman but now I'm a pilot so it would be my first Olympics in the role I'm in now, which is a lot more pressure.
"My break girls are the best, even if they rarely give me a moment of silence, and being a pilot now I understand the pressure of wanting to do well for them."
With Nicoll stepping up to pilot, it meant she was in need of some new breakwomen to help her.
And with her scouting hat on, the Welshwoman took a risk and approached two-time Olympian Ashleigh Nelson on Instagram.
The 34-year-old is of similar height and build to former breakwoman and Montell Douglas. But that's not where the similarities stop.
Nelson steps into the sled with an incredible athletics career already behind her, including two world, two European and two Commonwealth Games medals on her CV, with Douglas also a former sprinter, making her Olympic debut in the women's 100m at the exact same Games at Beijing 2008.
And after Nelson had an injury in the way of a third possible Olympics at Paris 2024, Nicoll's message seemed like an opportunity she couldn't refuse.
"British female sprinting is in an incredible position at the moment so you can't just get in the team by half training," she said.
"So when Adele messaged me and asked whether I wanted to give it a go, I was at a bit of a crossroads and I didn't know if I just wanted to have a rest and then go back to athletics, as I still haven't retired from it, or not.
"By October I was on ice, December I was part of the team and March I competed at the world championships."
Nicoll herself also still competes in athletics during the summer months before switching back to the ice for winter.
Where sprinting and bobsleigh seem pretty synonymous, shot put seems like there should be some major differences between the two, however Nicoll has noted that the two have more similarities than expected.
The shot putter lost 20kg to start her bobsleigh journey, but explained that the changing field in women's field event means that it is not detrimental to her own shot put success, winning three UK Championships since then and proving that the two sports go together like peas in a pod.
"I came from track and field into bobsleigh but I still do track and field now, so the goal is to be at to 2028 LA Olympics but I will have to see what that looks like post Milano Cortina," she said.
"I've understood along the way that I'm not a mass moves mass athlete when it comes to throwing and when you look at some of the best women in the world now, a lot of them are really lean.
"You have lots of different body shapes coming into the women's shot put now and that's really changing the sport."
With the attributes and skills between athletics and bobsleigh blending together, the one change that both Nicholl and Nelson have thrived off is being able to tap into the realm of teamwork.
Coming from an individual sport, that has a sprinkling of relay action involved, being able to jump in a sled with another person and have rely completely on each other's skills in a new and exciting opportunity of building something more than just the sport.
"Being part of a relay team is amazing but we're only together for a handful of weeks a year, whereas this is a pure team, day in and day out," said Nelson.
"Adele has my life in her hands at multiple times a day when she's driving me down and 80 or 90 miles an hour in a sled. You have to have trust then."
"I enjoy having a team of people to celebrate with," added Nicoll.
As the pipeline from athletics to bobsleigh continues to grow around the world, it's a summer to winter switch that athletes are thinking about more often, with London 2012 long jump champion Greg Rutherford having a crack at the sport pre-Beijing 2022 and long jumper Jazmin Sawyers winning Winter Youth Olympic silver in 2012 before making her change to athletcs.
And with the opportunity to use their athletics platforms to lift a winter sport that doesn't get as much media attention, Nelson hopes that her cold weather change can bring a whole new fanbase to bobsleigh.
"It's a brilliant sport that does get overlooked," she said.
"If I can use my athletics platform to put bobsleigh on the map then I'll be happy."
