Naemi & Alena Stump

Age: 14
Home country: Switzerland
Special skill: Skating

Hey, we’re Naemi and Alena! We’re twins who share a passion for synchronized inline skating. We've always wanted a hobby we could do together, and now we've taken it to the next level by breaking 2 world records as a duo! 🛼

How it all started…

We got inspired to attempt a record after reading about Fabiola da Silva, a Brazilian inline skater who broke the record for the most Summer X Games gold medals – 7!

But we used to think breaking a world record was impossible for us – especially after Alena got really sick when she was just 2 years old.

She's been getting bad headaches and has had trouble remembering things ever since...

But we didn’t let that stop us. 😎

Now we're 14, and we reach for our goals together as a team – and have so much fun doing it!

Our journey of record breaking…

We hold 2 world records:

Most synchronized tricks on inline skates in 30 seconds – 11
Most synchronized tricks on inline skates in 1 minute – 21

To prepare, we put together a sequence of tricks and practised doing them at EXACTLY the same height and skating at EXACTLY the same speed. 😬

Alena had a hard time memorizing all the tricks, so we practised the line together for weeks and weeks!

It takes hard work to reach the top. 💪

Dare to do something that you think is impossible. Never give up and always try to better yourself!

The day of the attempts

When the big day arrived, we were super nervous because we were afraid that we wouldn’t make it.

At the same time, we were so happy to even be given the chance to set a world record!

And thanks to our great friends we had lots of support, which made us feel strong and confident. 🙏

So when we finally broke the records...

We cooked dinner for everyone who helped us to thank them and celebrate together!

Fun facts about us

We’re not just about inline skating! We love all kinds of sports, such as:

Freestyle skiing 🏂
Skateboarding 🛹
Free skating and roller skating ⛸️
Ice hockey 🏒

In fact, when we were just 5 years old, we joined a local ice-hockey club and went on to play in national and international tournaments!

Pretty cool, right?!

Do you like any of the same sports?

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.

What it's like being record holders

Honestly, it still feels SO unreal to have not 1, but 2 world records!

We are very happy about it.

And what is more, we are featured in the Young Achievers chapter of Guinness World Records 2025 – what a dream come true! ✨
