Tailfin Cycling, a brand known for making frame bags and on-bike storage solutions for big, multi-day adventures, has created a choose-your-own-adventure bikepacking experience open to everyone.
Called Detours, the event gives you a starting point and destination, then lets you chart your own course between them (and back). Get as many miles in as you want, see what you want, and ride with who you want. All you need to do is make it to the overnight “checkpoint” to camp and hang out with everyone.

Tailfin partnered with A Cycling, the team behind Gritfest and Battle on the Beach, to launch Detours. They’re calling it a “community-focused bikepacking experience designed to celebrate freedom, self-navigation, and the thrill of charting your own course. Forget fixed routes and rigid itineraries Detours puts the adventure in your hands, challenging you to reach a shared overnight destination, your way.”

The event takes places September 12–14, 2025, starting and finishing in the UK’s Abergavenny area, South Wales. Riders will head to Forest Fields, Builth Wells, for the overnight stay with a single mandatory checkpoint along the way. Minumum 70km/45 miles per day. There’s no maximum – the routes are infinite, you just need to make it home in time for the cut-off.
More optional checkpoints let you “collect” stops if you want to extend the day’s ride, and the longest “detour” wins…it might just be bragging rights, but if you’re feeling competitive, there’s that. After the Saturday campout, everyone makes their way back to the start in one giant group ride on Sunday.
Three pricing tiers keeps it accessible to everyone:
- Standard rate – covers event costs
- Community rate – for those facing financial barriers
- Supporter rate – helps fund accessible spots for other riders
Participants can choose the rate that works for them…pay a little more if you can to help get more people involved.

To make it more inclusive, families, friends, and supporters are encouraged to join you at the overnight location. “Whether cheering from the sidelines, sharing a meal, or pitching up for the evening’s festivities, Detours is a weekend for everyone, not just riders.”
