Mike, who has been in the post since 2009, will stand down in six months time. He has made the decision in order to devote more time to cross-country course designing and consultancy work, having scaled back his designing work after being responsible for the track at the 2010 World Equestrian Games.
Among his other high-profile course-design jobs, Mike was designer at at the 2000 and 2008 Olympic Games.
“It’s no secret that my first love is being out and about on cross-country courses and I have been offered some more designing opportunities, including at the Adelaide four-star in Australia,” said Mike.
“It was a really tough decision to leave BE, but I feel that now is a good time for someone else to take over the reins.
“I’ve really enjoyed the job, which has been a real privilege, and would like to thank everyone in the sport, especially the staff at BE, for their commitment and support. I will always be more than happy to continue to help and advise where needed.”
BE chairman Hugh Thomas added: “Mike has done an outstanding job leading his team.
“I quite understand his desire to do more course-design while he’s still able, but we will certainly miss him a lot.”
Mike was previously event director at Blenheim, from 1990-2006 and Chatsworth from 1999-2007.
BE has said the position will be advertised “in due course”.
