The Bieg o Puchar Wójta Gminy Sieroszewice is a local running event in Sieroszewice, typically held on a Saturday in September. The main race is a 5 km run for the Wójt’s Cup, a field that can still perform well in poor weather; one edition saw a record number of starters despite rain.
The event is centered at the sports stadium in Sieroszewice and includes children’s races with distances suited to age groups. School pupils are a noticeable part of the day, and one edition had 170 children competing, with every child finishing and receiving a commemorative medal. The fastest adults in the main 5 km have achieved quick times, including a men’s winning time under 16 minutes and a women’s winning time just over 22 minutes.
