Immortal Triple Crown – Stourhead routes

Only the most hardened athletes will endeavour to complete all 3 elements over the weekend 10K, Mega Sprint and Middle Distance to secure a place in the Triple Crown Hall of Fame.

On completion of all three events, you’ll be inducted into the Triple Crown Hall of Fame and will receive a very special finisher’s memento.

Half -

This tough and challenging race will start off with a 1900m, two laps swim in the beautiful and scenic lake, followed by a 56-mile ride, which is stunning, yet fast and tough in equal measures. The route unusually visits the three counties of Wiltshire, Somerset and Dorset. The run route then follows a footpath through a meadow, before a section of tarmac to the far west end of the lap. From here the route passes through the woods to the west of Stourhead, on a lively descent. You will be again wowed by the views. Three laps take you past the stunning Estate House, where you are sure to be cheered on by friends and family. The finish line at the House at the end of lap three will bring with it, the accolade of becoming an Immortal Triathlete.

10K -

Around 50% of the route is on really quiet closed country lanes, with the remainder on forest tracks and trails. With a total of 770ft/235m of climbing

Running through Stourton village, then past the Lakes before taking a right turn crossing a dam before starting the run for the trees. In early May the flora and fauna is guaranteed spectacular, and the sights and smells will distract you from the shift you are putting in!

The loop through the forest takes in some beautiful clearings and pasture before returning to the Dam which supports the lake, under the Stone Arch before returning through the village and onto the driveway to receive the respect and applause from the gathered spectators and families.

Mega Sprint -

This tough and challenging race will start off with a 900m swim in the large lake, followed a by a beautiful and fast 18-mile ride through the Wiltshire, Somerset and Dorset counties, before finishing in a 4.5-mile run!

    • Did the Half Ironman in 2019

      Great venue, very well organised and fantastic Marshalls. Its a tough course but some of the views are amazing and the run through the woods is stunning.
    • Did the Half Ironman in 2019

      A brilliant day, clear routes, well supported, and a gorgeous setting. A fantastic place to do a half ironman.Details: running route half shade / half open was excellent, and a 'left turn only' cycle route made that safer and easier. Good planning. What would I do differently? Advise the water temperature before (if you did, I missed it), have registration for an hour the evening before (say 8-9?), if need be in a local pub for the sanity of your team, a few more loos, and food stalls with more food - they ran out early because they couldn't keep enough food on site for 2 days, but I thought they were really good providers, so don't change them! (that's why they ran out...)
    • Did the Half Ironman in 2019

      A hard course, so good for a challenge. Cycle and run courses very good. Marshals excellent - friendly, helpful and encouraging. Better signage to the car park would be good.
    • Did the Half Ironman in 2019

      Amazing experience. I didnt enjoy the mass start swim (dont enjoy swimming that much) but other than that a fantastic event with plenty of support and info to help you around
    • Did the Half Ironman in 2019

      fab. suggest having more nutrition/ gels available for the early runners - it was the third lap before an energy drink was available. amazing day, thanks
    • Did the Half Ironman in 2017

      A well organised event let down a little by the bike course. Although pretty, the road surface wasn't the best and there were two sets of roadworks that year (2107). The feed station (on the bike) was not ideal. The route was changed last minute for 2018 so 2019 could all be different. Great location and support as always though.
