Motivation with principles
Collect, yes. Pressure and risk, no.
Knurrix rewards long-term consistency and varied training. There are no rewards for dangerous heat or packing as many tracks as possible into a short period.
The stamp pass remains part of your protected account and never publishes a precise map of your training locations.
Quick answers
What you should know about the stamp pass.
Do my previous tracks count?
Yes. Tracks already mirrored to your Knurrix account count retrospectively. Tracks that were never mirrored or have been deleted cannot be included.
Are my stamped places public?
No. The stamp passport belongs to your protected account. Exact GPS tracks and training locations are never published through it.
Do I have to train unusually often to earn badges?
No. Knurrix rewards long-term consistency and variety, never unsafe volume in a short time or training in dangerous heat.
Which achievements count?
Regions, times of day, steps, consistency, surfaces, articles, ageing times and training milestones are among the areas considered.
