About this route

A 29-kilometre mountain-bike loop on the twisting forest tracks of the Uetliberg above Zürich. The many direction changes make it an ideal file for the animated replay with auto-rotate and auto-center. Speed is lower and more variable than the road ride.

This route follows real roads and paths in Uetliberg forest, Zürich, generated with the BRouter engine over OpenStreetMap data. The timestamps are synthetic, so it is a demonstration file rather than a personal recording. Route geometry © OpenStreetMap contributors, ODbL 1.0.

Common questions

Why use this file for replay?

Its constant direction changes show off auto-rotate and auto-center, which keep the camera aligned with travel.

Why is the average speed lower than the road ride?

Singletrack is slower and more stop-start, so the mean of the per-point speeds comes out lower.
