UK half marathons
The UK is home to hundreds of half marathons each year, ranging from iconic big-city races to scenic countryside runs. For many runners, 13.1 miles is the perfect distance — a real test of endurance, but still achievable with the right preparation.
Across England, Scotland, Wales and Northern Ireland, there are half marathons to suit every type of runner. You’ll find fast, flat city courses that are perfect for chasing a PB, charity-driven events with huge crowds, and breathtaking rural routes that take you through some of the UK’s most beautiful landscapes.
