    Solo swimmers need a long base with several swims of 4 to 6 hours and a practiced feeding routine from a support boat.

    Rottnest Channel Swim training questions

    How long should I train for the Rottnest Channel Swim?

    Most athletes give a open-water swim eight to sixteen weeks of focused training on top of an existing base. The coach counts back from your actual race date, so if you have less time than that it builds the best plan the remaining weeks allow rather than pretending you have longer.

    What is the Rottnest Channel Swim course like?

    How cold is the water at the Rottnest Channel Swim?

    The Rottnest Channel Swim does not publish a typical water temperature. The athlete guide gives the wetsuit rule for race day: check it before you plan your open-water sessions.

    Do I need an account to get a Rottnest Channel Swim training plan?

    Start as a guest and save a free account later. Your coach writes your open-water swim plan and adapts it every week as you log your training. No card.
