What the bike leg asks of you
Rolling, with a climb from the dam each lap: stay steady and eat on the highway.
How to prepare the bike leg
The general shape of a good bike preparation, which Event Coach turns into a plan for your fitness, time and date:
- Train long, steady power: the 180 km of Ironman New Zealand are ridden well below threshold — most age-groupers hold around two-thirds to three-quarters of their FTP — so the marathon is still possible.
- Ride your long sessions in the position you will race in, and practise eating and drinking on the bike: on race day you fuel the run on the bike.
- Add short runs straight after some long rides (brick sessions), planned around your bike training — Event Coach prepares the bike; your swim and run are yours to fit around it.
Pacing mistakes to avoid
The mistakes that cost triathletes the most on the bike:
- Riding the first hour of Ironman New Zealand on adrenaline: the watts you spend early come back as minutes lost on the run.
- Surging on every hill and every overtake instead of holding an even power.
- Under-eating on the bike: the energy for the run has to go in before you get off it.
