Great Eastern Run Half Marathon 2026 Entry, Date & Race Info

The Great Eastern Run is a popular UK half marathon held in Peterborough, known for its flat, fast 13.1-mile route and strong PB potential.

Starting in the city centre, the course follows wide, closed roads through Peterborough before heading into surrounding residential areas and parkland, offering a consistent and uninterrupted running experience. The largely flat profile makes it one of the more reliable options for runners targeting a personal best or even pacing effort.

With excellent organisation and a lively race-day atmosphere, the event attracts a mix of experienced club runners and first-time half marathon participants. Crowds build in key sections, particularly near the start and finish, helping create a motivating environment without overly congested running conditions.

Well regarded on the UK running calendar, the race often sees high demand and can sell out, particularly as runners look for fast autumn half marathon options.
