Race Preparation

We have partnered with experts in tri gear to help you kit yourself out for race day, whether through hiring or purchasing.


We advise participants of the water temp two weeks before each event. Both shorties and full-length wetsuits are acceptable but should not exceed 5mm in thickness. Please note that a tri-suit is not an alternative to a wetsuit.

As all of our adult cycle routes are on public roads, we recommend that you hire or buy a road / race bike for your race.

The children’s cycle route always takes place within the Castle Estate boundary and as such off the public road and free of traffic.  We recommend mountain bikes although some use a cyclo cross bike (effectively a racer with off-road tyres). The courses encompasses a complete mix of terrain but not too technical (e.g. no bunny hopping logs or super steep descents).

Cycle helmets are compulsory for all.
