(Swim)run & Sauna with Susanne Najafi & World Champion Staffan Björklund
How to start TechArena days in the best possible way?
With a morning (swim)run together with Susanne Najafi and Staffan Björklund.
Susanne Najafi is a serial entrepreneur, Founding Partner at BackingMinds VC and a swimrun athlete - two years into the sport and now gearing up to compete in the World Championships 2026 - showing that it’s never too late to start and push your limits!
Staffan Björklund is a true icon of the swimrun community: a long-time racer, endurance athlete, and leader in the sport. With a lifelong passion for adventure and endurance disciplines, he has competed at the highest international level, raced ÖTILLÖ – the Swimrun World Championship dozens of times, won the mixed category, and built a career pushing physical limits across swimrun and adventure racing. Today, he leads ÖTILLÖ as Race Director, bringing deep experience from both the course and behind the scenes to help shape one of the world’s most respected endurance events.
Together they’ll lead the way on a moderate-paced run in centre of Stockholm where swimming is optional but gladly encouraged. This is about moving together, not racing each other. All levels are welcome - complete beginners to seasoned athletes.
It’s winter and it will be cold - so we’ve fired up the sauna to warm up properly after the swimrun. Robin Ramm, unicorn founder, dedicated swimrun athlete and free diver - will lead an ice-plunge and breathwork session.
To support recovery, performance and long-term health, LOOVI - our longevity partner - will be on site, bringing a science-backed perspective on resilience, recovery and sustainable performance.
Come and start the best days of the year in the best possible way.
Spots are limited. Participation is by approval only.
Location and practical details will be shared exclusively with confirmed participants.
What is actually ÖTILLÖ?
ÖTILLÖ is where swimrun was born.
What started in the Swedish archipelago as a wild challenge between friends has grown into a global endurance phenomenon. ÖTILLÖ literally means island to island - and that’s exactly the point: running and swimming through raw nature, with no transitions, no shortcuts, and no separation between you and the elements. Known as the hardest races in the world.
Please note: This is an external side event at Techarena 2026. The location is outside of the Strawberry Arena. The side event is independently organized and run by the host of the side event. Please direct any questions (or praise!) to the event organizers.
