The Middle Distance Triathlon fits the Island as though Mersea was created for such an event!

Distances are the same as the half Ironman. The swim starts on the Jetty and takes competitors along the beach. The Cycle will take competitors off the Island along scenic Essex country lanes and over Abberton Reservoir before heading back to the Transition to begin the final leg. The Run for this event is effectively half a Marathon in distance.

Our unique Middle Distance Triathlon finishes with the run, around Mersea Island, the run distance is the exact circumference of Mersea Island. This is a flat triathlon but the terrain is a mixture of road, sand and seawall making it a unique but challenging course.

This is a great event for the more experience triathlete but is also a challenge for endurance lovers. It is also a fantastic event to enter as a relay team. Corporate packages are available.

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 southernmost tip of the Peckforton Hills. 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, 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.

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.

The debut Outlaw Half Holkham event in 2016 received 99.5% positive feedback and was an instant hit at the beautiful Holkham Estate. 2017 was bigger and better! The event takes place over a stunning course covering a 1.2 mile lake swim, 56 mile bike and 13.1 mile run, which can be completed as an individual or relay team of three competitors.

The Holkham Estate and its magnificent eighteenth century hall provide a stunning backdrop to the swim, both transitions and the run. The bike course is a single loop taking in the coastal road, quiet country roads and some faster roads. The run does feature some climbs across three loops around the Estate.

There is on-site camping organised specifically for competitors and their family and friends, camping is only permitted in Holkham twice a year, so this is a fantastic opportunity. There are various types of accommodation in the area, but this is a popular holiday destination, so please book early!

This will be a very high quality racing experience, and an escape from everyday life. Holkham is one of Britain's tourist gems, and we're delighted to be able to return for a third year.

The rapturous reception afforded to previous Castle Howard Triathlons subsequently led to the expansion of a 2-day weekend extravaganza.

In its 9th year, the Castle Howard Triathlon will be the 4th weekend event of the 2018 Castle Tri Series and will once again feature the obligatory picture postcard backdrop and a course with something for every level of triathlete. The 13,000 acre grounds of Castle Howard form arguably the most physically demanding triathlon course of the Castle Tri Series.

Race entrants will start the race by swimming through Castle Howards Great Lake before transitioning into the technical bike route through the glorious rural idyll of Yorkshire and the 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. Theres never been a better time to visit Gods Own County and Castle Howard.

The construction of Castle Howard took more than 100 years before being finally completed in the 18th Century, and spanned the lifetime of three earls and numerous architects, although Sir John Vanbrugh is credited with the original design. The Great Lake is the setting for the swim section of the triathlon.

Set in the Howardian Hills, the bike legs initially take in the 18th Century Avenue, a main road that runs in a straight line from south to north for five miles. The run will pass The Temple of the Four Winds and one of the finest, free-standing mausoleums in Europe. A hop over New River Bridge, a circumnavigation of South Lake and the Atlas Fountain will take racers to the finishing straight in front of Castle Howard itself.

Castle Howard has been a regular backdrop for films and television, with both ITVs lauded Brideshead Revisited in the early 1980s and the acclaimed 2008 feature film production shot on location here, hence the name of our adult races.
