~80% of training in Z2. Re-test every 8–12 wks.

Fueling & gut-training — build 60 → 100 g/hr

Practice fueling only on long rides / bricks / long runs — the gut trains like a muscle. Add ~10 g/hr every 2–3 wks. Above 60 g/hr you need a glucose:fructose mix (~2:1) (Maurten / Precision / SIS) — drink most of it + gels. Sodium 500–1000 mg/hr, fluid 500–750 ml/hr. Fuel by the clock: ~25 g every 15 min.

Rules that matter most

  • Consistency > heroics — show up for 24 months, finish strong.
  • Never miss two in a row.
  • 80/20 — most hours easy (Z2).
  • Recovery weeks are training — don't skip the down-weeks.
  • Fuel & sleep are sessions too.

When life happens

  • Sick above neck: easy OK. Fever/chest: rest.
  • Exam crunch: 3–4 maintenance sessions, keep frequency, never zero.
  • <6 h sleep / trashed: go easy, keep the session.
  • Missed a long one? Rejoin the plan, don't cram.
  • Niggle → pain: back off early.

Your kit

2006 Cannondale Ironman 2 — tri/TT bike (Slice Aero frame, Profile aero bars, Dura-Ace bar-end shifters). Already aero — a tri fit is the upgrade (dead traps = aero-position/core). Brooks Adrenaline GTS 26 (replace 500–800 km).
