If you've been putting in miles along the Grand Union Canal towpath or through Cassiobury Park, you'll know that Watford is flatter than most of Hertfordshire, and that makes a difference at the half marathon distance.

It's one of the better spots in the region if a PB is what you're after. If you'd rather build up first, 10k runs in Watford are a good place to start.
