ATW Watford Half Marathon
ATW Watford Half Marathon is a half marathon with a 10K and a short fun run, held in Watford, United Kingdom, in February.
Everything starts and finishes in Cassiobury Park, on the edge of Watford. The half marathon covers 13.1 miles on fully closed roads. It heads out through the lanes behind the Grove Hotel and golf course, passing Bucks Hill, Commonwood Common and Chandlers Cross, then returns to the park.
The 10K is a multi-terrain route. It uses traffic-free roads, then turns off near the 4k mark onto the towpath of the Grand Union Canal, with about 3km along the water and through woodland trails. The fun run is a 1.8km loop inside the park and is open to all ages. The half marathon also doubles as the Hertfordshire Vets championship race.
