The best runs that you've never heard of
To celebrate Global Running Day, we're rounding up the best unsung marathons, half marathons and more in the UK!

Global Running Day takes place in 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 every day 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 find more runs on TimeOutdoors than any other type of event.
That means 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!

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.

The Ciderthon
Henley-on-Thames, Buckinghamshire
August
If the name isn't enough to draw you in, here's what you need to know: this half marathon heads out from the Culden Faw Estate and takes in a varied, multi-terrain route that culminates at an event village complete with music, bars and entertainment. Sound good?
The Great Barrow Half Marathon Challenge | 10 in 10

Yorkshireman
Keighley, West Yorkshire
September
Running out of Haworth in West Yorkshire, the Yorkshireman is, aptly enough, a properly tough marathon. You can expect over 3,000ft of ascent over 26.2 miles of fell running, including some steep ascents but also some spectacular views! There is also a half marathon(ish) on offer, too.
