Dorney Triathlon routes
The purpose-built lake is perfect for the swim and the flat grounds lend themselves to a totally flat bike and run course, the ideal venue for a chip-timed PB. Each discipline will be accurately marked out with distance flags and we will have plenty of helpers to keep you on track and encourage you all the way to the finish.
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.
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 2 out and back loops, alongside the lake. The course is on pavements and is completely flat.
