The Castle Triathlon Series has grown from strength to strength over the last ten years, being recognised for their stunning courses, iconic venues and atmospheric event festivals. The new run offering gives runners the chance to benefit from the ever popular sport weekend with hundreds expected to take on the timed race.

Race Director Brian Adcock says, “Welcoming runners to our established triathlon events is a natural progression, after ten years of bringing triathletes from all over the UK, Ireland and France to our historic, stunning castle venues. Each run course at our castles has become iconic in the triathlon world, and we’re pleased to be opening these up to runners this year. Our family friendly multi sport festivals, with a triathlon distance for everyone, will welcome the addition of half-marathon and 10k runners to every castle in 2018.”

Castle Run Series races will each incorporate spectator friendly loops of beautiful countryside, a lake, and quaint and historic villages and of course a castle (or two!). Each runner will receive a medal and will be welcomed across the finish line with a banquet of well-earned treats, with live bands, food stalls, a retail area and camping at the castle making the weekend a festival of sporting achievements.

Runners can sign up now, making use of a 10% discount on all race entries which ends on 30th March 2018. To find out more and sign up visit
