Nick was born into the saddle. His father, Richard Mitchell is a licensed trainer with over forty years experience and has enjoyed success with horses such as Cool Ground, Capers Lad and Rooster Booster. His mother, Elsie Mitchell, was a very accomplished equestrian rider who then turned her skills to be a successful amateur jockey. His elder brother, Tim Mitchell, was a highly respected amateur jockey with over 200 wins to his name. Repeatedly vying for the Point-to-Point Rider's Championship when enjoying a long association with Richard Barber, the pinnacle of his career came whilst winning the Cheltenham Foxhunters on Fantus. He now works for the Racing Post. Finally, Nick's younger sister, Sophie, was Champion Lady jump jockey 2 years running and among her accolades are 2 'Lesters' for Lady Jockey of The Year. Now married to Guy Upton, John Jo O'Neil's assistant, she lives at Jackdaws Castle with Guy and her 2 sons Richard and Patrick.

Nick himself had an 18 year career as an amateur jockey with over 100 winners to his name, riding winners for, amongst others, Paul Nicholls and Robert Alner. He rode winners at Cheltenham, Wincanton and Sandown (Ride of The Week on At The Races) and Perth. One of his greatest thrills was completing the National course at Aintree.

After achieving A' Levels at college, Nick worked as Pupil Assistant to his father at Whitcombe Manor, Dorchester. In 1996 the opportunity came for Nick to train point to pointers as a private trainer at nearby Milton Abbas. He enjoyed great success over the next four years gaining invaluable experience running a yard culminating in a 32% win strike rate, with 60% of those coming first or second. In 2000 he spent a short while with the all conquering Paul Nicholls yard which 'opened his eyes' regarding the training of a racehorse.

Later that year came the opportunity to join the well respected yard of Robert Alner as his assistant. Over the next 7 years, whilst working with such horses as Kingscliff, Sir Rembrandt, The Listener and countless other top quality jumpers, Nick familiarised himself with all that is required to train under the expert eye of one of the best stockmen and judges of thoroughbreds in the business.

The plan was always for Nick to train under his own name and on completion of his Trainer Modules in 2007, the opportunity arose in his home village of Piddletrenthide, Dorset. Nestled in the bottom of the valley on Piddletrenthide Estates, a purpose built yard of 21 boxes was completed in 2008 when Nick was granted his license. After an admittedly 'tricky' first year things are now progressing nicely; with very good second season statistics, including a Grade 1 and Listed Chase winner in the bag. The new all weather gallop now installed means that new horses are arriving and plans to expand are being discussed. Nick feels he is finally in a position to train horses 'as I've always wanted to'. Nick is married to Lucy and they have a daughter, Nancy and 2 sons, Gabriel and Dominic.
