The Watford Half Marathon is a very well-established race, its mainly along lovely country roads and lanes that are virtually traffic free.

UK Athletics Gold Graded Event

The race will incorporate the Hertfordshire Veterans Championships (place of birth or 9 months residency) 




Race Photos are available here: www.SussexSportphotography.com 



Please note that the course was adjusted in recent years to eliminate the area that was prone to flooding. Because of road closures runners must be capable of completing the course within three hours.

It will be an ideal preparation race for London or other spring marathons.

DID YOU KNOW: Last year's winner Paul Martelletti went on to break the Guinness World Record as the fastest marathon runner dressed as a superhero in 2 hours 29 minutes!
