Running of the wha?!
It's by far the most important sporting event in London this summer.
Forget what you think you know about the Running of the Bulls, this event on London's Hampstead Heath is like the bastard child of a pub crawl and a run in the park - with lightning-fast athletes instead of raging bulls.
It'll be a great day full of fun taking in some of the most historic pubs in the most beautiful part of the best city in the world.
Take the bull by the horns!
This summer will see the inaugural Running of the Bulls UK, and we need your help to make it a day to remember.
If you want to run with bulls, make sure you sign up to our Facebook event.
If you're not on Facebook, please get in touch to let us know you're coming.
But we also need volunteers to help us put this thing together.
We're keen to hear from video and photography experts, journalists, bloggers, tweeters, PR bods, web developers, designers and copywriters.
Whatever you can do to help, get in touch and apply to be a volunteer.
