Velký Bolevecký rybník (Bolevák), Plzeň, Czechia (Copyright © 2017 Hendrik Böttger /


The Maraton okolo Boleváku ("Marathon around Bolevák") takes place in Czechia's fourth-largest city, Plzeň, which is in many countries better known as Pilsen.

Held at least twice per year (in March and in December), the event offers a 10k race, a half marathon and a marathon. The March edition also features a 50k race.

The route runs around the Velký Bolevecký rybník (or Bolevák), the largest of the Bolevec Lakes which were created in the fifteenth century.

Situated approximately three and a half kilometres to the north of Plzeň's historic centre, Bolevák is a popular place for leisure and recreation all year round.

One lap around the lake is 3,230 metres.

The 10k is three laps plus 310 metres, the half marathon is six laps plus 1,720 metres, the marathon is thirteen laps plus 205 metres, and the 50k is fifteen laps plus 205 metres plus a 1,345-metre out-and-back run.

Starting at the Autocamp Ostende at the western end of the lake, the race is run on a mix of asphalted and paved cycleways and footpaths.

The course is flat.
