ATW Watford Half Marathon & 10K

Step into the heart of Watford on February 7th, 2027, for an unforgettable running experience at Cassiobury Park. The Watford Half Marathon, 10K & Fun Run offers something special for every runner and their supporters.
The day begins with a vibrant 1.8km Family Fun Run around the picturesque park grounds, perfect for young athletes and families alike to enjoy together. This event is designed to foster community spirit and provide an encouraging environment where everyone can cheer on little runners.
For those seeking more distance, the multi-terrain 10K follows alongside the Half Marathon participants as they leave Cassiobury Park onto traffic-free roads. The route splits at around the 4km mark, guiding you down to the serene towpath of the Grand Union Canal for a peaceful stretch along its calm waters. Afterward, runners will venture into woodland trails that offer quiet beauty and tranquility before finishing back near event HQ where supporters’ cheers can carry them across the finish line.
The Half Marathon itself is an awe-inspiring journey through Hertfordshire’s countryside lanes. Starting in Cassiobury Park, it ventures beyond to explore Bucks Hill, Commonwood Common, and Chandlers Cross. The route loops back into the park for a stunning finish. Runners must adhere to a cut-off time of 2 hours and 45 minutes at the 11-mile mark due to road reopening requirements.
This event also hosts the Hertfordshire Senior Half Marathon Championships, open only to those born in or residents of Hertfordshire for over nine months. Participants should declare their eligibility during registration.
Adding excitement throughout the course are lead cars and cyclists ensuring smooth navigation. The Watford Half Marathon has earned a prestigious 'Racecheck Gold Award' based on high participant reviews, reflecting its commitment to quality and safety.
Alongside scenic routes and challenging terrain, runners will enjoy live musical entertainment featuring an energetic drummer along with other performances that boost morale throughout the race day.
