Dorney Lake in Windsor is a 2,200 metre flat water rowing lake owned by the well-renowned Eton College. Used for many international regattas, and famously hosted the Rowing events during the London 2012 Olympics.
Starting and finishing outside Dorney Lake Boathouse all three disciplines are within the grounds of Dorney Lake. This swim follows a 750m loop around once or twice before taking to the cycling course along the left side of the lake and finishing with a flat and fast run up and down the right side of the lake.
Dorney Lake is ideally placed being within easy reach of London, Heathrow Airport, the M4 corridor and the M3, M25 and M40 motorways. It is well served by the rail network with main stations being Slough, Maidenhead and Windsor. Taplow and Burnham train stations are also nearby.
There will be free parking for all participants next to the event village and start and finish!
Whether you have a charity in mind, or would like our help, you can have a look around and find the charity you’d like to support. the charity will support you every step of the way and give you that bit extra to make sure you become a hero on race day!
BTF (British Triathlon Federation) rules apply. All these rules are important but the most important of these is that all competitors must secure their cycle helmet (on their heads!) before removing their bike from the rack and must not undo or remove it before racking their bike at the end of the cycle section.
You must also fully comply with and follow all rules of the Highway Code. Our primary consideration is your safety, make it yours as well!
You will be guided to the side of the lake at the swim start, straight after the race briefing.
Swim hats are compulsory and will be provided.
You will be asked to enter the water and line up at or behind the start line. The swim will start in the water.
The start will be prompt, to provide the most accurate times for you.
The temperature of the lake is taken on the morning of the event and if it is over 14c then wetsuits will be optional. If the temperature is over 22 degrees then wetsuits will not be allowed. Please don’t email us if wetsuits will be allowed at the race, as we can’t tell you this information until the temperature is taken on race day.
If you have any recent exposed cuts or feel unwell you are advised not to take part.
If you get into any sort of difficulty, roll onto your back and raise one arm directly upwards out of the water. This will prompt a lifeguard in a kayak to either rescue or attend to you out in the open water.
The route is clockwise. The course will be well marked with swim buoys and you will complete 1 lap for the sprint distance and 2 laps for the standard distance. After completing your correct number of laps, you will head for the swim exit marked by flags.
After securing your cycle helmet in the transition area, (this must be done before un-racking your bike), proceed on foot to the mount point, where you must wait until it is clear to start the bike course.
You must ensure you mount and dismount correctly, (i.e. after the mount line and before the dismount line), failure to do so will result in a time penalty!
The 5km bike loop will be completed 4 times for sprint distance athletes and 8 times for standard distance athletes. It is your responsibility to count your own laps. We find the best way of doing this is with the aid of a bike computer or watch.
Starting from the transition area, triathletes will run either 1 or two out and back loops, alongside the lake. The course is on pavements and is completely flat. There will be 1 drinks station on the course, manned by marshals serving water in plastic cups. This is the only drinks station and you will pass it on each lap.
After the Race No bikes can be removed from transition until the last cyclist has returned in your wave. Your number must be presented to remove your bike. There will be no exception to this!
Toilets - There will be toilets a short distance from the transition area.
Baggage - There will be an informal baggage drop area for you to leave any belongings within the transition area.
Spectators - You are free to wander around the lake so you can see where the competitors will be running. It is lapped so you will see them on numerous occasions.
Results - Event Chip Timing will record your times. Results will be live at www.eventchiptiming.co.uk throughout and after the race.
Prizes Presentation - The presentation of prizes will take place throughout the morning and we’ll make announcements prior to the presentation. There are lots of prizes on offer!
Pictures - We will have a photographer taking a few snaps of the race and they will be on our Facebook page after the race so be sure to check it out and see if you can spot yourself.
