How to Know If You’re Ready for Your First IRONMAN70.3

Signing up for your first IRONMAN 70.3 is exciting—and it can feel a little scary too. The race includes a 1.9km swim, 90km bike, and 21.1km run, so it’s no small feat. The swim alone makes most people cautious about it.

The good news? You don’t have to be fast or elite to take on a 70.3. What you need is a solid base, a structured plan, and the mindset to stay consistent.

Ultimately - if you have followed your training then you are ready for your first IRONMAN70.3. Especially if you were working with a coach.

If your still feeling unsure - read further.

Common Myths That Hold People Back

❌ Myth: “I have to be fast to finish.”
❌ Myth: “I need a tri bike and top-end gear.”
❌ Myth: “It’s too late to start.”

Reality? Plenty of athletes finish their first 70.3 using basic gear, averaging moderate paces, and starting from square one. The key is consistency—not perfection.

How to Start Where You Are

Start by assessing your current fitness. Focus on aerobic endurance, not speed.
- Build your long run and ride gradually
- Add in one strength session per week
- Practice open water swimming if possible
- Track your recovery and listen to your body

You don’t need to train 20 hours a week. You need to train smart, recover well, and fuel consistently.

Final Thoughts

The best time to start preparing is now.

If you’re even thinking about signing up, you’re probably more ready than you think. The biggest leap isn’t in fitness—it’s in deciding to go for it.

Believe in your ability to grow stronger with each session. Your finish line moment starts with one step.
