My first half marathon. Loved it. Jeff C

Superbly organised from bib collection to toilet queues, excellent communication pre the event, fabulously scenic route, amazing encouraging Marshall's AND FREE photos! I’ll definitely be back again a race that was very much enjoyed by myself and many others. Thank you. Faye R

The Watford half is a well organised race.. There are lots of marshals who are all happy and encouraging. Which always helps when tackling some of the hills! Plenty of local parking. Love the option at ATW to add a race t-shirt. The pacers are a great addition too. Petra W

I love the Watford Half, great organisation and a lovely undulating route. Kath E
