Královská Desítka

K10 sport, z.s. organizes Královská desítka, a community running event held in Královské Poříčí. Designed for a wide range of participants, the race welcomes both beginners and experienced runners. Its main event is a 10-kilometre course, while Poříčská trojka offers a 3-kilometre option for adults and young runners who prefer a shorter distance. Children can take part in races over 250, 450, 910 or 1,365 metres, and the youth events are part of the Karlovy Vary Region Youth Running Cup.

Although the 10-kilometre course is not a road race, its profile is intended to support fast times. The route is certified by the Czech Athletics Federation, so performances can count as official personal bests. The organizers also provide prize money for leading competitors in the main race. Their experienced team draws on participation in races in the Czech Republic and abroad. After the event, runners and spectators can relax together, with food and drinks available at the venue.
