Vltava riverside path: Smíchov to Troja via Kampa Island, approximately 18-20km one way. Distance markers along route, mostly flat with Prague Castle views across river.

Petřín Park loop: 4-5km forest trails with serious 318-meter climb to the Petřín Lookout Tower (Prague's mini-Eiffel Tower). Hill training with reward views over red-roofed Malá Strana. Early morning before tourist crowds.

Divoká Šárka: Natural trail running through rocky valleys northwest of city. Red-marked trail loop about 5km through limestone gorge. Take metro A to Dejvická then bus 218, but feels like countryside.
