Cholmondeley Castle Triathlon

Saturday 23rd and Sunday 24th June 2018

The 2017 Cholmondeley event attracted over 1500 competitors to the beautiful countryside of Cheshire,  offering the quintessential Castle Triathlon Series experience of competitive and fun racing, an epic castle backdrop and a stunning rural location.

All races at the 200-year-old Cholmondeley Castle start by launching into an open-water swim in Deer Park Mere Lake, transitioning on to a bike route that circumnavigates Bickerton Hill, which is the southern most tip of the Peckforton Hlls. There will be one cycle lap for the Super Sprint and two laps for both the Sprint Plus and Olympic distances.

The run passes through the estate grounds, which date back to the 12th Century, and has one lap for the Super Sprint and two laps for the Sprint Plus and Olympic races. Triathletes will finish their Cholmondeley race experience by sprinting down the main lawn to the finish line with Cholmondeley Castle as a fitting backdrop.

About Cholmondeley Castle

The Cholmondeley Castle Triathlon takes place in the beautiful grounds of Cholmondeley Castle, where the Cholmondeley family have resided since the Norman era of the 12th Century.

The estate features extensive parkland covering 500 acres including two lakes, the larger of which, Deer Park Mere, is the setting for the open-water swim section of the triathlon.

To the south of Cholmondeley Castle, Tower Hill is the highest point of the run section, where athletes will be rewarded with panoramic views of the Beeston and Peckforton Hills, which they will have just covered on the undulating bike section, with the Welsh Hills looming in the distance.

Please note that Cholmondeley Castle is a private residence of the Cholmondeley family and is not open to the public.

We also delighted that this year the Senior Mixed Team Relay, the new format used in the commonwealth games, will be the North West Championship event. Taking place on the afternoon of Saturday 23rd June, will see four person teams; two males and two females, each completing a 250m swim, 5km bike and 1.5km run as part of a tag team.

Mixed Relay has proven extremely popular with athletes of all standards and allows regular age groupers and more advanced athletes to race together. The minimum age requirement for athletes is 15 years. There is no upper limit upper age limit or ability for those taking part.

Go long for the Gauntlet

The 2017 Gauntlet, half iron race pushed competitors to their limit via a 1.9km swim, 90km bike ride and 21km run and we look forward to it’s growth in 2018.

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.

Castle Swim Series

Saturday 23rd June 2018

The swim only event provides the choice of three different distances: 5km 2.5km and 1mile (see price table below) and boasts a unique and stunning swim route in all the stunning castle lakes.

The swim described by many triathletes as the ‘best open water swim ever completed’ will now be open to outdoor swimmers as an event in its own right.

All swimmers will be provided with timing chips and the races categorised into wetsuits and non-wetsuits. Prizes will be awarded for the top three male and female competitors in each distance.

One mile leisure and family swim

Enjoy the beautiful setting of Cholmondeley Castle at your own pace. Swim any stroke you like (breaststroke encouraged), swim and chat with friends as you go around. Don’t worry about how long it takes (however time limit set at 90 minutes), just enjoy it. Under 16s welcome if accompanied throughout by a competent responsible adult.

Castle Run Series

Sunday 24th June 2018

The Cholmondeley Castle Half Marathon will see competitors undertake 3 laps of the spectator friendly 7K estate loop.  Starting adjacent to the cricket pitch and in full view of the castle the 1st K of the course follows a well worn track to an area of the estate called Cattle Crush.  At this point and for the next 4.5K runners follow the internal estate tarmac road that takes them past the estate chapel, the Old Hall and out to the Beeston Lodge Gate before they double back and head towards the castle itself.  After passing the huge Victorian stable and supporting dove-cote runners will head uphill to the landscaped area behind the castle before turning right and heading steeply off-road up to the top of Castle Hill which affords a view of the stunning Peckforton Hills to the north of the estate.  The final 1K of the circuit is mostly downhill off road passing the castle tea rooms, over the croquet lawn and down the main lawn of the castle.  With the finishing line in sight runners turn left at the fork and continue around for the 2nd and 3rd laps.  Finally, with third lap complete, runners turn right into the finishing straight and cross the finish line with the castle as a backdrop, to receive their medal and the now famous finishing line banquet!

The half marathon – 13.1 miles takes place at all our venues (UK, Ireland and France) in 2018 on the most iconic and stunning off road, spectator friendly courses

Wow! What a great event Cholmondeley was again! Well organised, a strong competitive field, yet an intimate and friendly event. We are looking forward to trying out some of the other venues.
