The Series

Hever Castle Triathlon

The UK’s third biggest triathlon, the world’s largest children’s triathlon and the finale of both the Castle Tri Series and the UK triathlon season.

Hever Castle Triathlon

Saturday 27th and Sunday 28th September 2014


We can take on the day entries. See Race Admin page for full details.

In just five short years the Hever Castle Triathlon has swiftly established itself as an essential destination for British and international triathletes, garnering plaudits and mainstream media attention for its picture postcard venue, elite action, age-group choice and festival atmosphere. Put simply, instant classic doesn’t do the Hever Castle Triathlon justice.

With no fewer than 13 race choices on offer, over 5,500 triathletes ventured to Hever Castle in September 2013, with entries increasing again for the fifth running of the event in 2014. To cement the race’s title as the world’s largest children’s triathlon, 2,000 youth athletes are expected in September, up 30% from 2013. In 2013 the children’s race places sold out in August so places have been expanded this year by splitting the children’s races over two days (8-10 year olds on Saturday afternoon and 11-15 year olds on Sunday afternoon).

For 2014, the Gauntlet Half Iron Distance is back for a second time after a stellar debut last year, with the new long-distance Bastion heading to Hever Castle on the 13 July.

The races will again commence with an open-water swim in the spectacular 38 acre Hever Castle Lake, transitioning into the undulating cycle that takes athletes around a 20km circuit through the High Weald of Kent, an Area of Outstanding Natural Beauty, with one lap for the Sprint and two laps for the Olympic-distance racers. The largely off-road run circumnavigates the estate and award-winning castle grounds before making the dash to the tree-lined finishing chute beside the lake.

About Hever Castle

Famous for its links with the Tudors, particularly Henry VIII, there have been three main periods in the construction of this historic castle.

The oldest part of the castle dates to 1270 and consisted of the gatehouse and a walled bailey. In the early 1500s the Bullen family acquired the castle and added a Tudor dwelling within the walls. Hever Castle was also the childhood home of Anne Boleyn, the mother of Queen Elizabeth I.

In 1903, William Waldorf Astor restored Hever Castle, building the Tudor Village and creating the gardens and Hever Castle Lake, which plays host to the swim section of the triathlon and took 800 men to dig by hand and took two years to construct.

Since 1983, the castle has been owned by Broadland Properties and is now open to the public. The castle itself houses historic 16th Century Tudor portraits, furniture and tapestries, and two magnificent prayer books inscribed by Anne Boleyn.

Film buffs will note that Hever Castle provides the a backdrop to 1987’s fairytale comedy classic The Princess Bride, starring Cary Elwes and Robin Wright, and 2008’s Inkheart with Brendan Fraser.

Go long for the Gauntlet

The 2014 Hever Castle event will witness the exciting introduction of The Gauntlet, a middle-distance race that will push competitors to their limit via a 1.9km swim, 90km bike ride and 21km run.

The race distance had a hugely successful launch in 2013 at the Chateau de Chantilly and Hever Castle Triathlons, with hardened triathletes and newcomers to the triathlon and middle-distance racing side-by-side on the start line.
