The Green Belt Relay is a 22-stage running relay race around 220 miles of the Green Belt around the outside of London over a single weekend.  The course mainly follow footpaths, towpaths or minor roads.

It is organised by The Stragglers running club, has been going since 1995, and involves around 50 teams.  Runners form teams of 11 people, and each runner runs one stage each day.

Although the race is a relay, each stage starts at a fixed time.  This allows each stage to be a competitive race in its own right, and also allows teams of all different standards to stay roughly together as they advance along the route.

The race takes place over 2 days, Saturday and Sunday, 13 and 14 May 2023.

2023 will be the 25th running of the event
