TrailFest Holdenby House
The TrailFest Holdenby House on 13 September 2026 in Northampton, offers a 10km, Half Marathon, Marathon and 50km Ultra Marathon distance.
The different distances all use the same parts of a 10km course within the private grounds of the Holdenby House estate, starting and finishing between the Basecourt Arches.
The course takes runners through fields on a mixture of farm track and field edge, through woodland sections, one noticeable hill and amazing views over rolling Northamptonshire.
