Marathons Found In Watford
View all ↓Marathons in Watford 2026 - 2027
The most comprehensive list of Marathons in and near Watford in 2026 - 2027. Find your perfect race!
The Grand Union Canal towpath runs straight through Watford and keeps going for miles in either direction. Head north out of the city and you get flat, uninterrupted running with nothing to manage except your pace. Cassiobury Park and the River Gade path give you more varied ground when you need it. Between the two, you have most of what marathon training requires. Prefer to build up first? Half marathons in Watford are a good starting point.
Browse the listings below and pick one that works for you. Watford isn't a destination marathon city, but the flat Colne Valley setting makes it a decent option if you're chasing a time. For a shorter effort, try 10k runs in Watford or 5k runs in Watford first.
