Yes, the Prague Marathon is a certified Boston qualifier. The course is net-neutral and has produced fast times, so it's a reasonable choice if you're chasing a qualifying standard on a good day.

The time limit is 7 hours, which gives most runners a comfortable window to finish.

The course is close to net-neutral with a modest 65 feet of net elevation change. There is cumulative gain of around 623 feet spread across the loop as small rollers rather than one big climb, so it rewards even pacing over the full distance. Some sections run on cobblestones through the historic center, which requires a bit more focus underfoot.

Early May in Prague is generally cool, with temperatures at the start in the upper 40s and afternoon highs near 60. Conditions are usually favorable for running, though rain is possible. Check the forecast before race day, especially if cobblestone sections are on the course.

Recent editions have seen around 7,600 finishers, with a capacity of 10,600 registered runners. It's a substantial field but not overwhelming, and the wide riverfront stretches give plenty of room to run your own race early on.

The race starts at Old Town Square, which is directly accessible via Prague Metro line A (Staroměstská station). Václav Havel Airport is about 20 km west of the city center, roughly 20 to 30 minutes by shuttle or taxi. Staying in the Old Town or New Town district puts you within walking distance of the start.
