Mistrovství světa veteránů v běhu do vrchu - nahoru/dolů

The World Masters Mountain Running Championships Up/Downhill race is a 9 km mountain run in Janské Lázně, a spa town in the Trutnov District of the Královéhradecký Region of the Czech Republic. It takes place in late June, with the first category starting at 9:00 AM, and it is designed for masters athletes, not an open city-road crowd. The start is on Svobody Square in Janské Lázně, near the Municipal Office. The format is up/downhill, meaning runners must manage both climbing and descending, rather than just reaching a summit. The event is part of the World Masters Mountain Running Championships, with Karel Šklíba listed as the organizer.
