The Olympic – Standard distance

About The Olympic

The Olympic/ Standard distance race, is hosted at all Castle Series venues with entries open to individuals and relays.

For first timers at this distance, it is both the obvious progression from the sprint distances and a perhaps a journey towards an extreme triathlon dream. The Olympic courses challenge triathletes to pit their wits against a 1.5km castle lake swim, a 40km hilly bike ride and a 10km off-road run at each of the Castle Series’ stunning venues and their scenic surrounds.

Following fantastic feedback from elites and age-groupers alike, the Olympic distance is our most popular course where we witness thousands of competitors do battle over the five stunning locations, making it the biggest standard distance race series in the UK.

If the promise of a cycle over the North Yorkshire Howardian Hills, a swim in the iconic Chateau Grand Canal or a 10K run though the historic grounds of Hever Castle whets your appetite then see below for a detailed course description of each of our five Olympic races.

The courses

1.5km / 40km / 10km

Lough Cutra Castle - Sunday 12th September 2021

Arguably the finest castle in the series – Lough Cutra Castle – provides a fitting backdrop for the curtain raiser of the Castle Series. What’s more, the race coincides with a Bank Holiday in both the UK and Ireland and it is also the first weekend of the UK school half term, making it an ideal break for sporty families.

The 1.5km swim takes place in the castle lake which just happens to be the largest privately owned lake in Europe!  The cycle heads out onto the Burren and provides a supremely fast and flat course as long as the wind isn’t blowing off the Irish Sea!  Finally the run takes in a 5km circuit of the castle grounds and estate.

Cholmondeley Castle - Sunday 20th June 2021

The UK Summer Solstice welcomes the second leg of the Castle Triathlon Series which takes place at Cholmondeley Castle in Cheshire during the long, hopefully hot, bucolic days of June.

The Standard Distance includes a 2 lap swim of Great Mere Lake (including an Australian exit and entry at the half way point) which sits in the lee of the castle itself, followed by a 2 lap cycle of the very fast 22km cycle course which includes a circuit of the Peckforton Hills and finishes off with 2 laps of a 5km circumnavigation of the beautifully manicured estate grounds.

Castle Howard - Sunday 25th July 2021

The Castle Howard Triathlon will finish a memorable July in style with a whole weekend of racing on the southern border of the North York Moors.

Race entrants will start the race by swimming 2 laps of a 750m course in Castle Howard’s Great Lake before transitioning into the technical bike route through the glorious rural idyll of North Yorkshire’s Howardian Hills. The spectacular run leg passes through the undulating countryside of the estate before a sprint finish tops everything off in style right in front of the main doors of the house on the North Lawn.  A truly inspiring event!

Château de Chantilly - Sunday 29th August 2021

The Castle Triathlon Series makes its yearly pilgrimage over the English Channel in August for the fifth race of the Series. Set over the UK bank holiday weekend and the end of August, the racing will take place in the spectacular and historic town of Chantilly, just a 2.5hrs drive from Calais and 40 km north of Paris.

At Château de Chantilly the course has a strong off road run element but is kinder than the Hever Castle course to competitors with a flatter cycle and run. The 1.9km swim in the Grand Canal offers the ultimate backdrop of the Château and its stunning formal gardens.

Heading out of the estate grounds on the Rue Vaillant the cycle course circumnavigates the Foret de Chantilly and Forêt Domaniale d’Ermenomillean with an equally stunning 45km loop. Culminating in a single lap 10.5km run course competitors will take in the vast estate park designed by Le Nôtre for the Grand Condé at the end of the seventeenth century and the contemporary gardens including the aptly named Jardin de Anglais.

Hever Castle - Sunday 26th September 2021

The UK’s most stunning and sought after triathlon, the world’s largest children’s triathlon and the finale of the both the Castle Series and the UK triathlon season. Hever Castle Triathlon 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.

For the Standard Distance, the 1.5km swim will involve a single loop taking in the main Hever Castle lake and a tributary of the river Eden. The 40km cycle is a hilly 2 loop 20K course taking in the stunning high weald of Kent and surrounding villages.

The 10.5km run course is a single loops of 10.5km that will take in the existing 5km Hever Castle Triathlon course but with a 5km extension via tracks and bridle paths and though the historic local village of Chiddingstone and grounds of Chiddingstone Castle.  The course includes a strong off-road element which allows a highly inspirational setting often praised and welcomed by the elite triathletes taking part in the Olympic distance.
