Questions

Is Kliva free?

You can use everything today without paying. Later, some race planner features will become part of a paid Kliva Pro plan.

Does it work with my watch?

Yes. Download a Garmin course (FIT) with your aid stations and markers from My race plans, or use the Connect IQ data field on your wrist for aid and fuel alerts, and cutoff alerts when The cutoff is selected. No Garmin? Email support@kliva.run with your watch model: other brands are on the way.

Which races are covered?

Trail races across Switzerland, France, Belgium, Spain and beyond, with more countries added regularly. No race listed? Drop a GPX and plan it anyway.

Do I need an account?

You can explore freely. An account saves your plans and syncs them to your watch.
