Who is behind it
I'm Peter. I ride ultras myself and this is my home region.
Shores & Switchbacks grew out of two things: I like this kind of event, and I come from a region that is made for it. Lake Constance, the Bregenzerwald and the Nagelfluh range lie so close together that lakeshore, forest and mountains can come together in a single loop.
What interests me about ultras is less the hero story and more the mix of self-reliance, a bit of nonsense, good people and long days on the bike. I want to bring that together in a format that fits the region.
Everyone who starts should get a good ultra: a route that challenges and rewards, and a Base Camp by the water that is a good place to arrive.
The region
Lake Constance, the Bregenzerwald and the Nagelfluh range.
The route is not finished yet. These three landscapes are fixed. The rest will keep moving until the loop really works.

Base Camp · Ruderclub Lindau
Start, finish and meeting point at the Kleiner See.
Ruderclub Lindau · Aeschacher Ufer 31 · 88131 Lindau
Our Base Camp will be at Ruderclub Lindau on the Kleiner See. Right by the water, quiet and with exactly the Lake Constance atmosphere the weekend should have. Not an anonymous event compound, but somewhere you actually want to stay for a while.
This is where Thursday's Riders Briefing, Friday morning's start, the finish and Sunday's shared event close will take place. Family and friends are welcome. Beyond the shared meals on Thursday and Sunday, we will not offer catering on site, but there are plenty of leisure options right nearby.
Camping: If logistics allow, we plan to offer a limited number of simple camping pitches close to Base Camp. Capacity will be limited and the pitches are only confirmed once the organisational details are final. Reservation details will follow with registration.
Participation
Small, visible and with more room for diversity on the start line.
Deliberately small
Shores & Switchbacks is not meant to become a mass event. Participant numbers will stay deliberately limited.
Live
Live tracking and a public leaderboard are part of it. For everyone who would rather watch dots on maps than sleep.
