ATW Holdenby House Duathlon

The ATW Holdenby House Duathlon is a scenic multisport event held on the historic 2,000-acre Holdenby Estate in Northamptonshire, England. Participants enjoy a traffic-free 5.4 km run through picturesque trails and farmland with views of the 16th-century Holdenby House. The bike course features a 19 km rolling route on fast country roads outside the estate.

The event offers two race options: a Sprint (5.4 km run, 19 km bike, 5.4 km run) and a Standard distance (10.8 km run, 38 km bike, 5.4 km run), with the Standard also available as a relay. Finishers receive custom medals, and the event supports Alzheimer's Research UK charity. Visit the organization's website for the most recent information.
