WHY SGRAIL?

The question people ask us most is: what's next? Which title or record are you after? Truth be told, we’re here because we love this sport and all its diversity — the nerves before a race, the new adventures, and the joy of the process of getting to those days. That’s when nature becomes our playground, and "getting lost" out there is a beautiful part of the journey. That’s where SGRAIL comes from: hours of exploring with friends, pushing each other — but never just for a personal best. Sitting down after a magic day, as a community, sharing stories over a coffee or a beer.
— Jan Frodeno
