30-Week Ironman Training Plan: Extended Preparation

A 30-week Ironman training plan provides extended base-building time for athletes who want a more gradual progression or are new to endurance sports.

Seven months of structured training allows for a conservative buildup that reduces injury risk while developing the deep aerobic fitness needed for 140.6 miles. This plan is ideal for first-timers, athletes over 40, or anyone returning from a break.

Who Should Use This Plan?

This 30-week plan is ideal for:

• First-time Ironman athletes wanting extra preparation
• Masters athletes (40+) who recover more slowly
• Athletes returning from injury needing gradual buildup
• Those with limited training background in endurance sports
• Athletes who can only train 8-12 hours/week consistently

If you're experienced and time-efficient, consider the 24-Week Ironman Plan.

Common Questions

Can I skip sessions?

Life happens. Priority order for missed sessions:

1. Long bike (never skip)
2. Long run (rarely skip)
3. Brick workouts
4. Threshold sessions
5. Easy sessions (okay to skip)

What if I get sick?

• Skip training entirely when ill
• Return gradually (50% volume first week back)
• Don't try to "catch up"
• Listen to your body

Can I race during training?

• Olympic distance: Good training race (weeks 14-20)
• Half Ironman: Excellent prep race (week 16-18)
• Sprint: Anytime as hard workout
• No racing in final 4 weeks
