Where does it start and finish?
A fast, flat loop starting and finishing on the riverbank in the Old Town, crossing the Vltava several times with castle views.
Where should I stay?
Staré Město (Old Town) puts you within walking distance of the start; Malá Strana is quieter and just across Charles Bridge.
How do I get from the airport to the start?
PRG airport is ~35 min via the Airport Express bus to the centre; no rail link, so allow time on race morning.
What else is on that weekend?
Friday/Saturday expo at the O2 universum, an easy shakeout across Charles Bridge before the crowds, and the running-festival atmosphere along the river.
