Seb Spencer grew up around racing, with a jockey mother, an aunt in the industry and his grandfather, trainer Neville Bycroft, all shaping his early understanding of horses. He began his own career as an amateur jockey, riding three winners trained by his grandfather, before moving into an assistant trainer role and later taking out his own trainer’s licence in 2018. Since then, Seb has built a strong record as a trainer, including notable winners such as Archduke Ferdinand at Newmarket, while continuing to develop the family’s racing legacy in his own way.

Dale brings over 20 years’ experience in racing, having ridden winners on both the Flat and over jumps.

Tess started her racing life at 15, joining Herbert Jones in 1975 before spending many years with Jimmy Fitzgerald, where her love of National Hunt racing grew around top-class horses and a yard she learned a great deal from. She later worked for Paul Midgley, mainly with good sprinters, with a career highlight being taking her favourite horse to race in Dubai. After COVID, Tess semi-retired and found her way to Seb’s yard, drawn in by the enthusiasm for the future and the chance to be a small part of a good team moving forward.

He first got involved with Seb through Mac Racing, a racing club they set up with the help of Seb’s grandfather. Little Muddy and Muddy Lynn were the two main horses in those early days, with Seb training both to win races for the club. After taking holiday from his transport job to go racing whenever they ran, he eventually made the move to work for Seb full time. Alongside his role at Chalkstone, he also runs the racing community DigiRacing. He enjoys being part of the yard for the team, the horses and the facilities, and is looking forward to a strong season ahead.
