Half Marathons 2021 - 2022
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. So whether you’re after a low-key local race or the excitement of a major event, check out our comprehensive 2021 - 2022 calendar below and use the “Refine” button above to fine-tune your search.

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.
What are some of the best half marathon races?
The half marathon calendar is packed full of popular races with thousands of runners taking part. Huge events like the London Landmarks Half Marathon, Cardiff Half, Reading Half Marathon and the Bath Half offer superb atmospheres, inspiring routes and cheering crowds at the finish line: but there are scores of smaller races to choose from too.
