The organizers of the marathon have issued a forewarning about potential disruptions.

Last Generation, a group of climate activists, intends to demonstrate at the Berlin Marathon.

Jürgen Lock, the managing director of SCC events, hopes for a peaceful event but is prepared for demonstrations.

Last Generation disrupted rush-hour traffic at 20 locations in Berlin recently.

They also sprayed the Brandenburg Gate orange as a form of protest.

A group member was sentenced to eight months in prison, and others received shorter sentences.

Last Generation is demanding a transition away from coal and fossil fuels by 2030.

Germany aims to become climate-neutral by 2045 but has missed targets for the last two years.
