Ultra marathon UK events

We will assume if you’re considering ultra marathons, you’ve already got a grasp of where to look for them.  But, as 12in12.run are here to help, the links on this page acts as a starter list to get your planning underway.

Remember to check with the event you enter publishes their results online, as you’ll need to submit the website link for verification by the 12in12.run team. We wouldn’t want one of your runs to go uncounted.

Don’t forget to check that your event is classed as an Ultra before you book it. Whilst some say anything above a marathon distance is considered an Ultra, the event must be deemed an Ultra for it to qualify.

There’s plenty of sites out there, so we have listed few as the vast majority will contain the same events.
