Geofyzikální běh

The Geofyzikální běh begins at the Velký altán pavilion in Krčský les, a large forest park in Prague 4. This cross-country and trail race takes place in early September, offering separate distances for men and women: 6 km for men and 3 km for women. The men's race consists of two 3 km loops along a varied forest path, with only about one-tenth of the route on asphalt. Women complete one loop of the same course. SABZO Praha organizes the event, with Aleš Špičák noted as an organizer. The race has a long local history, with over forty editions having been held.
