Morning light spreads over limestone meadows as riders set off along the Gacka River, the current whispering and nudging them forward. Electric assist eases the climb; gravel kicks up behind the tires; an old Douglas Dakota sits quiet in a field, a surreal waypoint in a ride defined by contrasts — open river plains, scattered watermills, and low karst hills.

Manage battery with reserve
Start in a conservative assist mode and switch to higher power only on hills so the battery lasts the full 35 km.
Bring water and snacks
There are few services along the route; carry at least 1–2 liters and a compact lunch for a 3–5 hour ride.
Choose closed-toe shoes
Field roads and brief off-bike sections can be rocky; sturdy shoes protect ankles and provide better pedaling control.
Respect private land and springs
Stay on the marked route and avoid entering private properties or fragile springheads to protect trout habitat.
Reusable water bottle
Keeps you hydrated between sparse services along the 35 km route.
