In the north, it was the corooooons... Well, maybe we went a bit too far north! 😅 Welcome to Stockholm, Sweden, for the Adidas Stockholm Half Marathon! 🇸🇪 You are invited to the capital of 30,000 islands to celebrate the end of your vacation in style: with sports! 💪 Halvmarathon means half marathon in the language of Zlatan ⚽️. That's the distance you'll have to tackle: 21 km winding 🐍 through the various islands of the beautiful Swedish city 🏝️. Don't worry though, the course is pretty flat: perfect for breaking your record! 🥇 Moreover, temperatures are mild at this time of year, contrary to what one might think ☀️.
Urban Tribes was founded by professional running coaches in Stockholm who believed group running could be simpler, more welcoming, and genuinely fun. Their philosophy is straightforward: run together, move people forward. Coaching expertise meets collective energy every time the tribe laces up. The crew draws runners from across Stockholm who want structured guidance without losing the warmth of a shared run. Led by coaches who know how to keep the group moving and motivated, Urban Tribes has built something real where the tribe feeling starts from the first step and keeps runners coming back.
Run Collective Stockholm launched in November 2022 with a radical belief: running works better without hierarchy. Founded on the principle of pure democracy, every member holds an equal vote and shared ownership. No captains, no gatekeepers, just runners deciding together. The crew has grown to around 70 members, blending native Swedes and internationals in a warm, open community rooted in Swedish culture. They run twice weekly: Tuesdays at 18:15 from Bacchi Syre and Saturdays at 10:15 from Biscuit Konditoriet. The vibe extends far beyond the kilometre itself, built as much around post-run conversation as the miles that bring them together through Stockholm's streets.
