Welcome to the Watford Half Marathon, organised by Watford Harriers.

Weather Notice
We have had 4cm of snow overnight but remain optimistic and continue with preparations for the race but please check the website for further updates on Saturday.

Please note the changes to the course to avoid the flooding experienced in 2014 and that numbers and chips are to be collected on the day at the race H/Q.

This year we have chosen the Watford Peace Hospice as our chosen charity and would be delighted if you were able to support this very worthy cause, a sponsorship formis available via our website www.watfordhalf.co.uk

Please note that this year’s race HQ will be in a marquee adjacent to the finish. There will be toilet, baggage, refreshment and changing facilities here, but regrettably there are no shower facilities.

Limited parking is available in the car park at the rear of the Town Hall. There is also a car park at the centre of the nearby roundabout by the entrance to the Town Hall and at Rosslyn Road car park, all very close to race HQ. Please use these car parks in preference to parking in the surrounding streets and thereby help us to maintain good relationships with our neighbours. A map showing the location of all car parks is available here.


We would like to thank all of you for entering this event. If there is any way in which you think we could improve the event, please let us know.

Please check our website, Facebook or Twitter for any last-minute instructions.
