FAQs

What’s the priority for Ironman training?

Sustainable volume and recovery. Long-course fitness is built by repeatable weeks, not occasional hero days.

How do I avoid burning out?

Keep intensity controlled, use cutbacks, and treat sleep and fueling as part of the plan.

When should I do long simulations?

Rarely and scaled. Your goal is execution practice without creating injury risk.
