Distance
Terrain
Arm Race Mazowsze takes place in Karczew, a small town on the Vistula river south of Warsaw, on Saturday 3 October 2026. Runners pick between a 5 km and a 10 km course, and each distance is offered in a competitive Pro classification and an open, less pressured Open classification. The 5 km also has a Fun category for runners who simply want to enjoy the morning, while Pomarańczowy Wojownik and Dzika Rodzinka add shorter, family-oriented formats to the day's programme. Everything starts and finishes in and around Karczew, and entry is handled through the Rajsport Active registration portal.

Other questions
Pro entries are the competitive classification, aimed at runners chasing a fast time and a place in the results. Open entries run the same course but without the competitive classification, which suits runners who want a relaxed day out. Exact rules are confirmed by the organiser.
These are additional formats on the race programme alongside the 5 km and 10 km. Pomarańczowy Wojownik (Orange Warrior) and Dzika Rodzinka (Wild Family) are shorter, family-oriented entries, usually aimed at children and parents running together, or at runners looking for a playful obstacle-style challenge. The organiser's website has the current definitions and age limits.
Aid station details for each distance are confirmed by the organiser closer to race day. For 5 km and 10 km road races, expect at least a finish-line water point and often one on course for the longer distance.
Yes. The courses are in and around Karczew, so friends and family can watch from the start and finish area and from points along the route. Course maps and viewing suggestions are published by the organiser.
The organiser decides whether the event goes ahead in difficult conditions and will communicate any changes on the event website and social channels. Races of this type normally run in rain, with only severe weather causing a change.
