MUM - Cimrmanova etapa

The MUM - Cimrmanova etapa is a July trail marathon held in Lomnice, Czech Republic. The race office and start are located at the town’s elementary school. It covers the standard marathon distance of 42.2 km and is one stage of Moravský UltraMaraton, a challenging Czech series featuring seven marathons over seven days. The official MUM website provides the stage route and a GPX file for runners to examine the trail course prior to the event in Lomnice. The race is also listed in Czech running calendars, has a Facebook page, and includes photo galleries from past editions. This aligns with its function as a recurring event within a small but demanding multi-day marathon series.
