ANECDOTE

From One Ironman To Pro In Two Years

  • Lucy went from a 12-hour first Ironman to turning pro within two years by dedicating more time to training and cutting work hours.
  • She bought a secondhand eBay bike, raced upright and un-aero, then systematically improved nutrition, equipment, and consistency to drop hours off her time.
INSIGHT

Aero Tweaks Trump Extra Training For Margins

  • Small aerodynamic tweaks on the bike can save significant time over 112 miles, often with no extra training.
  • Lucy saved ~20 watts in the wind tunnel by changing suit, helmet visor, and bike position, worth over three minutes in an Ironman.
ADVICE

Plan Training Blocks And Prioritise Consistency

  • Structure key weeks into focused blocks: prioritize swim most days, bike heavily during bike blocks, and run in moderated, consistent mileage.
  • Lucy typically trains 20–25 hours weekly, swims nearly every day, bikes most days, and keeps running around 60 km/week.
