Running a good half marathon time is something every runner has on their 'To Do' list. Whether it’s a trail race or a road race, a 13.1 mile half marathon is the natural next step up from 10k, and one of the classic benchmarks to test yourself against. It's long enough to be a true test of fitness, stamina, pacing, form and mental strength, but short enough to be within reach of anyone willing to train consistently for a couple of months. 

Our database contains everything from small, locally organised half marathons, to one of the biggest races on the planet - The Great North Run - which attracts over 50,000 runners and was the first mass participation event on the planet to reach 1 million cumulative participants. In all the Find a Race calendar lists over 350 half marathons every year all over the UK and beyond.
