The findarace.com calendar lists hundreds of 5k races across the UK every year - there's almost one for every day of the year. 5km is one of the most popular race distances, and with a bit of training its relatively achievable for most ages, shapes and sizes - as a result they make perfect family fun runs that multiple generations can take part in and enjoy.

A 5k race is also a perfect goal for a beginner or new runner who hasn't taken part in an organised race before - it's a great, fun introduction to the raceday experience. 5k races are also popular with more seasoned runners looking to keep their running short, sharp, and fast - we list the fastest and flattest 5km races in the UK (as well as the craziest and hardest).

Looking for 5k races tomorrow or this weekend? Sort the event list below by "Date" to see the soonest races, but please note many races don't accept on-the-day entries, and Organisers often stop taking bookings a several days (and up to a week) before a race so they have time to organise race packs, bib numbers, medals, water etc. If you're super keen to run with others this weekend but have left it too late for a race then you could check your local parkrun to see if it is taking place.
