Mark Spincer will become the new chief executive officer of Jockey Club Racecourses (JCR). He will replace Charlie Boss, who is leaving at the end of the year and will report to JCR group chief executive Jim Mullen. However, a formal start date for Spincer has not been set.

Formerly from Arena Racing Company (ARC), Spincer was managing director of the racing division there since January of 2020. He was also formerly group operations director and executive director of Newcastle and Doncaster Racecourses.

Mullen said, “Mark is a superb operator with 25 years of experience in the hospitality and leisure sectors and knows the racing industry inside out.

“This role requires an operational leader with an unwavering focus on customer experience and a track record of delivering racing and live music events across multiple sites.

“I'm excited to work with Mark to help get the best out of our highly motivated and brilliant teams across our portfolio of racecourses.”

Spincer said, “I'm delighted to be joining The Jockey Club and really looking forward to working with the teams there.”
