Large field marathons

Cardiff Half Marathon

With over 15,000 runners, the Cardiff Marathon is the best-attended road race in Wales.

Large marathon with an entry limit of 16,500 runners who all start and finish close by the Madejski Stadium.

London’s “other” marathon is a pretty major event in its own right.

A big marathon with around 20,000 runners all enjoying a route around Northern Ireland’s capital city.

One of the world’s great marathons – as simple as that.
