The Swim.

Swimmers at the edge of an indoor swimming pool, preparing for a race or practice, with spectators and other swimmers in the background.

  • ↠ Start times are based on your estimated 400m swim time with the slowest swimmers start first from 8:15am.

    ↠ The swim will be in a 4 lane, 25m pool. Competitors need to be in the swim holding area 15 mins before your start time changed & ready to collect your timing chip. The swim marshal will group the swimmers into waves, with 4 swimmers to a wave and each wave starting every 2-3mins.

    Please note: It is the swimmer’s responsibility to count their lengths. We will have a marshal randomly checking and counting lengths.

    ↠ The swimmers around you will be of a similar standard, but if you need to overtake then please check the opposite direction as there may be up to 4-5 swimmers per lane and we don’t want any collisions!

    ↠ You will be told which direction to swim in, on entering the lane. On completion of your 16 lengths, exit through the marked fire exit There will be no changing facilities. Follow the signs for the transition area (this is a 150m run on paths & grass, please be careful) and find you bike.

    ↠ The surface is tarmac & grass & will be swept clean, but if you want to wear shoes for this section then place your shoes outside the fire exit on exiting the pool. Swim hats are not supplied and are optional.

    ↠ The weather could be very cold for all competitors on race day whatever time you are starting. Competitors will be allowed to leave a cycling jacket/gilet and gloves outside the fire exit if they wish but please be mindful of your start time, so we don’t have 300+ items of clothing on the pool exit.
