Route details

The Tring Boundary Trail (‘TBT’) is a circular route which follows, as closely as possible, the parish boundary of Tring. It was devised by members of Tring Running Club in 2015 as part of the celebrations for Tring’s 700th anniversary as a market town.

The trail uses public footpaths, permissive paths and the canal towpath. There are a few short sections on lanes and roads. The total distance is approximately 45km or 28 miles.  However for this event the route has been reduced to a maximum of 21.7 miles.


The TBT can be followed entirely with the route descriptions. There are no TBT waymarks.  The route descriptions and a map for each of the distances for this event can be downloaded here;

The route description starts and ends at the memorial hall in Aldbury and the trail takes a clockwise direction.  The route will not be marked for this event in any way.


Tring Boundary Trail 2The trail is predominantly on public footpaths. There are numerous gates, kissing gates and stiles as well as footbridges. Part of the route is on the canal towpath. After rain, some paths can be very muddy!

The route follows or crosses several roads at which extreme care should be taken. No marshalling assistance will be provided for crossing roads and traffic will not be stopped. Some of the lanes and roads are narrow and bendy and drivers will not easily see walkers/runners.

The southern section has several steepish climbs and descents. The northern section is mainly flat.

Many paths cross agricultural fields and the state of the path will vary with the seasons. After ploughing, the paths may not be distinct on the ground. Likewise, when crops are growing the path may be obscured by growth. In warm weather, large cracks can develop in parched fields. At several points the public footpaths cross farmyards, stables and private gardens. Fields may also have farm animals in them.

Always follow the Countryside Code
