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.

The ninth Outlaw Triathlon is all set for summer 2018. One of Nottingham's key sporting events, the Outlaw has become (almost) even more legendary than Robin Hood, the Major Oak and Brian Clough!

Those who have conquered the Outlaw Triathlon are remembered in local folklore for having outwitted the Sheriff to complete a 2.4 mile swim, 112 mile bike ride and 26.2 mile run. As long as you can cover the distance in 17 hours or less, you will become an Outlaw. Six men have completed it every year since the Outlaw was launched in 2010; can they come back and finish it for a ninth time this year? And will you be joining them as a competitor or spectator?

The event begins with a mass swim start in the Regatta Lake at Nottingham's National Water Sports Centre. Its an out and back swim course which is easy to navigate. With transition right next to the swim exit you'll have every opportunity to set a super-quick time and even faster escape onto your bike.

The roads around Nottinghamshire are ideal for fast riding (time trial bike friendly) and there is only the odd short climb to challenge you, but dont underestimate the wind!

On returning to the National Water Sports Centre our merry men will rack your bike and see you out on to the flat run course around the lake and on to the River Trent path. You'll pass Trent Bridge, the City Ground, Wilford Suspension Bridge and the Victoria Embankment. The multi-lap course, which has been measured by UK Athletics, offers a feed station every mile or so, and is lined with supporters willing you all the way to the finish line.

On arrival at the finish you will receive a hero's welcome and be crowned a modern day Outlaw. Then you can enjoy the festival atmosphere with thousands of spectators cheering the athletes home until the sun finally sets on a spectacular day of racing.

Outlaw has been recognised as 220 Triathlon Magazine's Event of the Year in 2011, 2012, 2013, 2014, 2016 & 2017 and British Triathlon's Event of the Year in 2011.
