About the race

Tewinbury Trail 5K & 10K is a trail running event hosted at Tewinbury, a countryside hotel, restaurant and event venue north of Welwyn in Hertfordshire. The next edition is listed as TBC.

Both routes take place entirely on trails around the hotel grounds and nearby estate. The terrain is undulating and mixes single-track forest paths, open dirt tracks and grassy sections. Underfoot conditions are described as good, with short climbs and descents creating a steady rhythm through the course. Navigation is simple and supported by orange signage and marshals at key junctions.

Key facts:

  • 5K (100 m elevation)
  • 10K (180 m elevation)

The race is fully marked and marshalled, with chip timing and live results. An aid station offering water, gels and jellybabies is located at approximately 5.3 km on the 10K route; cups are provided. Other event provisions include onsite car parking, bag drop, medical support, on route photos and a finisher souvenir. Tewinbury provides pre and post-race refreshments at the finish.
