Taking racing to the next level...

Dorney Lake Run Series


Set at the spectacular, flat and smooth-surfaced Dorney Lake near Windsor, the course takes you around the perimeter of the iconic water. Join hundreds of runners at one of the most successful venues for Team GB 2012, be motivated by those champions and go for your 5k, 10k or half marathon PB.

The legendary Eton Dorney, as Dorney Lake was called by London 2012, held 30 events throughout the Olympics and Team GB won a total of 12 medals. Soak up the atmosphere, get inspired and cross the finish line to receive your own Dorney Lake medal.

Along with your souvenir medal, a variety of revitalising snacks and drinks to kickstart your recovery awaits you at the finish line. Grab a finisher's photo on our podium before you leave and watch out for your result within hours of the race.

This event is suitable for Wheelchair Users. You may be asked to start at the front of the field before the scheduled start time and be vigilant of other runners overtaking during the event.

Noise-cancelling Earphones/Headphones are prohibited and whilst we discourage the use of other earphones/headphones at this event, participants choosing to use them should ensure they are set to a minimum volume such that instructions from marshals or other event officials can be clearly understood. We reserve the right to disqualify participants who cannot hear instructions as a result of their use.

Whilst there is no strict Time-Limit for this event, in order that we adhere to the restrictions imposed by the venue hire agreement, it will be necessary for us to begin deconstruction of the registration/finish area(s) at approximately 13:30 to facilitate the removal of all equipment from the premises by the agreed time. Runners will therefore need to be able to complete their registered distance by this time.
