A JAW-DROPPING video showing two Hillingdon free runners clearing a track of obstacles designed for horses has gone viral.

In the video Shameem Abbas, 23, and Mason Green, 17, perform spectacular leaps and flips as they race around the 6.5 kilometre track tackling 45 solid fences on the Land Rover Burghley Horse Trials course in Lincolnshire.

Their video went viral with more than 280,000 views in just four days — posted on August 18, it's now on 297,000 views.

Land Rover Burghley Horse Trials event director Elizabeth Inman said: “The Land Rover Burghley cross country course is a demanding challenge for the world’s best horse and rider combinations, so the 6,500m of track was quite a feat for the free runners as well.

“I understand this was a very different environment compared with that which Shameem and Mason are used to practicing their tricks - they described it as countryside playground.”

Mr Abbas and Mr Green can be seen somersaulting over a ditch big enough to drive a Land Rover Discovery and balancing on some of the competition’s 2m by 1.40mhigh fences.

Mr Abbas, free runner and gymnastics coach at Botwell Green Sports and Leisure Centre, said: “Mason and I have trained together for a long time, we started free running around seven years ago.

“Running the Land Rover Burghley Horse Trials cross country course was honestly the most fun I have ever had.

“We are used to training in urban environments, usually all over London, so it was totally crazy to be out in the countryside doing something different.”

The elite horses and their riders who are used to track like this, many who have just returned from the Rio Olympics, will complete the same course at Burghley Horse Trials from September 1-4.

Jessica Hannen, gymnastics development manager for Better Leisure Centres said: “Shameem and Mason really demonstrate the versatility of gymnastics and how it is a sport for everyone. 

“They both practice hard in the gym and this video is the ultimate showcase for their skills.”
