Half Marathons 2020 - 2021
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.

How long is a half marathon?
Half marathon races are 13.1 miles or 21 kilometres, exactly half the distance of a full 26.2 miles or 42.2 km Marathon race. The average finishing time for a half in the UK is around 2:00 hours with more seasoned runners often pushing for 1 hour 30 minutes or less. This makes half marathons the perfect choice for runners looking to step up to a new challenge from 10k races and an important milestone for those on their way to running a full marathon.
