Do3 is proud to announce that on Sunday 8th August 2021 we will be holding the inaugural 'On The Edge Triathlon'. This is no regular triathlon, this is something special. The race is based in the grounds of Compton Verney stately home which provides a stunning backdrop to the swim and finish line. The swim takes place in the Capability Brown designed lake right in front of the main house. Once the swim is done it is out onto the 'On The Edge' bike course. The bike course is where this event gets its name as it features climbs and descents along the well-known Edge Hill escarpment. Once the bike course is completed competitors return to Compton Verney to start the run around the area local to the house before finishing in style on the beautiful lawns. A truly special race and one that offers it all.

The Course


1900m swim in the beautiful Compton Verney lake. With a deep water start, competitors will start in waves and complete 3 laps in front of the stunning Compton Verney house. 


A course with something for everyone. Flat sections for the time triallers and some cheeky climbs for the mountain goats! The ride will take you through the picturesque Warwickshire countryside and include some climbs and descents on the Edge Hill escarpment including infamous Edge Hill itself before returning to Compton Verney.

  • Distance - 54 miles

  • Total elevation - 2281ft

  • Road types and conditions - Mostly minor roads. Road surfaces are good. Any potholes etc will be marked.

  • Bike choices - Suitable for time trial/triathlon and road bikes.



The race will finish with a half marathon on the local roads, tracks and trails in and around the Compton Verney estate. This multi-terrain course has it all. Just the right amount of flats and hills to challenge you but also make the most of the beautiful local scenery. The undulating course will eventually bring you to the finish-line in front of the stunning main house. 

  • Distance - 13 miles

  • Total elevation - 782ft

  • Road types and conditions - Grass, tarmac and packed trails. If it has been dry then regular running trainers will be fine. If it has been very wet for a prolonged period it could be muddy in parts.
