Hammerhead and Bubbles will be heading to the Kia Oval on Friday 30 May, representing West Ham United in the MailOnline London Mascot Derby - and to celebrate, West Ham are offering fans a £5 discount on tickets to the NatWest T20 Blast.

The race, which is being run at half time in the T20 Blast match between Surrey and Middlesex, will pit Hammerhead and Bubbles against the likes of Chelsea's Stamford the Lion, Crystal Palace's Pete the Eagle, Billy the Badger from Fulham and AFC Wimbledon's Haydon the Womble from football - as well as runners from cricket, rugby and even The City - with Octopus Investments and NatWest also due to field entrants. There are currently 19 declared runners for the race!

Always a competitive affair, last year saw an eight-foot FA Cup taken out by a rampant Sarrie the Camel from Saracens and end up at the bottom of a large pile of aggressive furry critters. When rivalries are renewed next week, blood, fur and comedy feet could spill onto the Kia Oval's historic outfield!
