TRANSITION

Competitors are able to rack their bikes prior to their event in the designated rows within Transition.

Tri Star Starts will be laying bikes down in transition, all other bikes will be racked.

If this is your first triathlon we suggest you take 5 minutes to watch the below video on how to set up transition.

This walk is on a mixture of grass and tarmac and can either be done either in flip flops or barefoot. All competitors will be escorted across the bike course to the swim start prior to event start due to the crossing of the bike course.
