What you should know
- Full IRONMAN: 3.8km swim, 180km bike, 42.2km run with ~2574m gain — pace the bike conservatively to save the marathon.
- Bike and transition bags must be racked the day before; CE-certified helmet buckled before mounting or you'll be DQ'd.
- Wetsuit legality depends on race-morning water temp — bring a swimskin or sleeveless tri-suit as backup.
- Strict intermediate cutoffs (swim ~2h20, bike, run); missing one ends your day. Memorise them before the start.
- Mild 19°C Leeds weather can flip fast — stash arm warmers and a gilet in your bike bag for rain or windy descents.
