Take to the streets of London and run this fantastic 10k on fast, flat, closed roads.

The London Winter Run 10k is the UK's largest 10k race with over 20,000 people expected to take part.

So layer up and expect to be serenaded by penguins and polar bears, and pick up one of the best medals going when you cross the finish line on Whitehall.

Entries are now closed but you can always pop along to support your fellow Sutton Striders (and we suspect there'll also be the opportunity for a post-race 'celebration' afterwards!)
