Harrison is 10 years old from Hertfordshire. He is attempting to do 100 vaults on to a pony by the end of February! Harrison finds this really hard to do, so this is a massive task.

Harrison had Hand Surgery to re attach a tendon in October and still has to wear a hand splint every night. He has to have han therapy at the hospital every 2 weeks and only was alloud by the hospital to ride again on the 20th of January!

Once he has completed his task he aims to try to achieve 100 canter pick ups from his pony (pick up a ball from the floor whilst in canter!) 

Please follow the videos of his attempts and fails on Facebook Harrison Dickens racing and jumping journey and in Instagram @harrygoesracing
