Twin sisters make history with record-breaking skating achievements

Naemi and Alena Stump, twin sisters from Switzerland, have developed an extraordinary passion for synchronized inline skating.
Now 14 years old, the sisters first discovered their love for skating at the age of eight when they were searching for a shared hobby.
What began as a casual pastime has since evolved into something much more significant, as the Stump twins have set two world records on a vert ramp measuring 3.9 metres (12 feet 9 inches).
Their remarkable feats include:
- Most synchronized tricks on inline skates in 30 seconds – 11
- Most synchronized tricks on inline skates in one minute – 21

Naemi and Alena’s incredible talent has earned them a spot in the latest edition of Guinness World Records 2025.
When asked about the secret behind their extraordinary performances, the sisters explained: “You should know each other so well that you know what the other person is doing without having to communicate. The one who is better at the trick adapts to the other.”
The Stump sisters may make synchronized inline skating look effortless, but their journey to success has been anything but easy.
As the girls themselves admit, mastering their routines requires an immense amount of practice and dedication.
“We practise a lot to do the tricks at the same speed and the same height,” they shared.
In fact, they once believed holding a world record was out of reach. Alena’s journey has been particularly challenging as, at just two years old, she was diagnosed with a brain tumour, which left her with persistent headaches and memory problems.
Struggling with her memory made it even more difficult to synchronize complex routines. “Alena kept forgetting the order of the tricks,” Naemi explained.
To overcome this, they practised their routine together for weeks, allowing Alena to fully memorize the sequence of movements.
The day of their official world record attempts was nothing short of nerve-wracking: “We were very nervous because we were afraid that we wouldn’t make it. At the same time, we were overjoyed that we’d been given the opportunity to set a world record!”
What made the experience easier was the overwhelming support they received from their loved ones.
“Thanks to our great friends we had lots of support,” the sisters said.
After the attempt, they cooked dinner for everyone who had helped them reach their goal: “That way we could thank them and celebrate together.”
When asked how they felt about their incredible achievements, they reflected on the surreal experience.
“It still feels very unreal to have two records. We are very happy about it.”
Naemi and Alena Stump are not only record-breaking inline skaters but also multi-talented athletes who enjoy a variety of sports, such as:
- Freestyle skiing
- Skateboarding
- Free skating and roller skating
- Ice hockey
When it comes to ice hockey, the twins are seasoned pros. When they were five, they joined a local ice hockey club and went on to compete in both national and international tournaments!
After sharing their incredible journey, the Stump sisters wanted to offer some words of inspiration to all the young people out there chasing big dreams: “Dare to do something that you think is impossible. Never give up and always try to better yourself.”
Congratulations, Naemi and Alena, you are Officially Amazing!
