A trail 5K & 10K race at the delightful Tewinbury Farm & Hotel just north of Welwyn in Hertfordshire.

Our enjoyable trail routes follow a selection of brilliant trails around the estate and surrounding countryside.

The routes are undulating with a mixture of terrain to tackle, including single track forest paths and open tracks where you can accelerate off the hard dirt trails.

The route

Both our routes are entirely on trails surrounding the hotel grounds.

The terrain is undulating and has a fun rhythm between the ups and downs.

Underfoot conditions will be good with the route providing a nice mix of dirt, grass and woodland trails.

Navigation is simple and will be aided by marshals and our orange signage.
