The best runs that you've never heard of

To celebrate Global Running Day, we're rounding the best unsung marathons, half marathons and more in the UK!

BB Ultra

Global Running Day takes place on Wednesday 7 June and there are free events and virtual challenges happening across the UK throughout the week to mark this international celebration of running.

While Global Running Day may only come round once a year, we take to the streets and trails in our thousands everyday to head out for a run. British Cycling may have made more headlines in the past decade or so but it's running that we have a national obsession with, which is why you can more runs on TimeOutdoors than any other type of event. 

That means that as well as hugely popular events like the TCS London Marathon and AJ Bell Great North Run, you can discover a massive range of local races and fun runs that don't have a title sponsor but do have willing and enthusiastic organisers hosting a great experience.

Here, we're celebrating some of the best runs that you've likely never heard of, all of which you can sign up to right now!

Beacons to the Blacks

Half marathons

One of the UK's most popular distances, these 13.1-mile (21K) runs can be found across the country, both on road and on trails.

Grimsthorpe Gallop

Bourne, Lincolnshire
