If taking on the full team challenge, all team members complete all disciplines. The first team member will set off on the swim, come out of the water, tag the next member who then completes the swim and so on. You then move on to the bike and then the run.

If taking on the split team challenge once you decide who is doing what discipline the first team member will swim, then hand over the race chip to the 2nd team member at the handover pen and then the team member biking will do the same thing for the 3rd team member who will finish with the run.

Team Challenge Logistics:

Full team:

Group A starters must gather in Swim Pen at 8.55am. Here they will pick up their swim caps. Group B only moves in after Group A has started the swim. This is when they collect their swim caps and again the same for Group C. Each group will be given different coloured swim caps.

A starters must make sure they have the timing chip on (around their ankle). They start the swim 400m. Once finished they come back and tag B starters who are now in the Swim Pen having collected their swim caps. Remember to hand over the TIMING CHIP.

B now goes off for their swim and does the same.

Group A have to move over to the Bike transition and wait in the tag area.

Once Group C have finished the swim they have to run over to the Bike transition area and tag A (remembering to hand over the TIMING CHIP).

A goes off on the bike and completes 3 laps of Dorney Lake. (Helmets MUST be worn) Once completed they MUST dump their bikes at the BIKE DUMP RACK, and then run over to tag B, and again same for B. Once they have done this they MUST remove Bike from BIKE DUMP AREA to clear this space for the next group.

Once Group C finish the bike they dump their bike at the BIKE DUMP Rack and now run over to RUN PEN where Group A will now be. Again they tag A handing over the timing chip.

A now complete one lap of Dorney Lake 5km, coming back to tag B who are now in the pen.

C will complete the last lap and will come back and cross the finish line, completing the race.

Split team:

The first team member swimming must be in the swim pen. Once they come out of the water they run over to the bike pen where they hand over the race chip to the person cycling and after this person completes their 15k cycle they come in to transition then run over to the run pen (was initially the swim pen) and the last team member completes the 5k before crossing the finish line.
