The plan in brief

  • This free 16-week training plan for IRONMAN 70.3 Augusta averages 10 hours a week, peaking at 13 hours in week 11, with recovery weeks 4, 8 and 12 and a two-week taper.
  • It starts on Monday, 7 June 2027 and ends on race day, Sunday, 26 September 2027.
  • A typical week has about 10 sessions — three swims, three rides, three runs and, in the first half, strength — with the time split roughly 45% bike, 30% run and 21% swim; the longest ride is 3:30 and the longest run 1:40.
  • Adjusted for this course: rolling bike course; heat.
  • At the 2026 edition, 2,421 athletes finished; the median finish time was 6:09:21 (men 6:03, women 6:33), and the middle half of the field finished between 5:31 and 6:54.

swimbikerunstrengthfitness (42-day load)R = recovery week
Hours per week by sport. Volume builds for three weeks and drops by about a third in the fourth (R), so the work turns into fitness; the line is fitness, a 42-day average of training load. The taper lets fatigue fall faster than fitness, so you start the race with positive form.

Five phases

Baseweeks 1–4

Aerobic engine and technique. Mostly easy, a little sweet spot, strength on Mondays.

Build 1weeks 5–8

Threshold work on the bike and run, longer weekends, longer bricks.

Build 2weeks 9–12

Race-specific: long efforts at 70.3 power and pace, the biggest weeks of the plan.

Peakweeks 13–14

Race rehearsals: full fuelling, race kit, race pace off the bike.

Taperweeks 15–16

Volume drops, intensity stays. Arrive fresh, not flat.

Adjusted for this course

Rolling bike course

About 457 m of climbing. Ride your long rides on rolling terrain and practise holding race power over the tops instead of spiking it on every rise.

Heat

Race-day highs around 29 °C. From week 12, do two sessions a week in the heat (or overdressed indoors) to acclimatise, and practise drinking 600–800 ml and 600–900 mg of sodium an hour on every long ride.

Week by week

Every session with its duration and what to do. Key sessions are the ones to protect when life gets busy; the rest can move or shrink. Miss a few days? Pick the plan up where you are — don’t try to catch up.

CSS is your critical swim speed — roughly your pace for a hard 1,500 m. FTP is the power you can hold for about an hour. No power meter or test yet? Ride and run by the effort column.

Questions

How many hours a week do I need to train for IRONMAN 70.3 Augusta?

This plan averages 10 hours a week over 15 weeks of training (peak 13 h in week 11) at the standard level. The 7-hour version is enough to finish strong if you already swim, ride and run regularly; the 13-hour version suits experienced athletes chasing a personal best or a World Championship slot.

What finish time should I expect at IRONMAN 70.3 Augusta?

At the 2026 edition, 2,421 athletes finished; the median finish time was 6:09:21 (men 6:03, women 6:33), and the middle half of the field finished between 5:31 and 6:54.

Why are weeks 4, 8 and 12 easier?

They are recovery weeks: volume drops by about a third so the training of the previous three weeks turns into fitness instead of accumulated fatigue. Most age-groupers who get injured or burn out skip them.

How long is the taper before a 70.3?

Two weeks. Week 15 cuts volume by about a third while keeping some race-pace work, and race week keeps you sharp with short openers. In this plan form (freshness) rises to about +27 on race day.

What if I miss a week?

Pick the plan up where you are rather than catching up. If you miss more than a week in Build 2 or Peak, repeat the previous week before moving on. Protect the key sessions (the long ride, the long run and one quality session) when time is short.

Do I need a power meter or heart-rate monitor?

No. Every session has an effort (RPE) description. If you do have one, set your bike zones from an FTP test in week 5 and your swim pace from a CSS test in week 3.

What are the longest sessions?

The longest ride is 3:30 and the longest run 1:40, both in the second build block, with race-pace efforts inside them. You never need to cover the full race distance before race day.
