Half Marathons Found In St Albans
View all ↓Half Marathons in St Albans 2026 - 2027
The most comprehensive list of half marathons in and near St Albans in 2026 - 2027. Find your perfect race!
Half marathon training in St Albans is well served by the flat ground around Verulamium Park and the River Ver path, which give you consistent, uninterrupted miles for the longer sessions. The lake loop in the park and the river path heading out of the city both work well for building distance. Heartwood Forest to the north is a large woodland area with trails on hillier ground, useful when you want sessions with more elevation in them. Build up with 10K runs in St Albans before committing to the full half.
Have a browse through the listings below. Jersey Farm woodland park and the Cathedral precinct are both closer to the city centre, with wooded paths and a more compact urban option for shorter sessions. Marathons in St Albans are there when you're ready to go further.
