In Episode #543 of the Grit2Greatness Endurance Podcast, Coaches Rich Soares and April Spilde break down why Boulder is one of the most misunderstood and execution‑heavy races on the IRONMAN 70.3 calendar. This is a thinking athlete’s race—where small mistakes stack up fast under altitude, heat, and patience‑testing terrain.

We dive into the real reasons athletes DNF at Boulder, including:

• Overbiking relative to altitude
• Underfueling when effort feels “easy”
• Heat and hydration mismanagement
• Swim anxiety and disrupted breathing
• Aggressive early run pacing
• Missed bike lap cutoffs
• Ignoring early warning signs

You’ll learn how to race Boulder with restraint, patience, and intention—so you’re still strong when it matters most.

We also debut a new fun segment: “Death, Taxes… or DNF?”—calling out the most predictable race‑day mistakes we see every year.

If you’re racing Boulder 70.3—or any altitude event—this episode is your race‑proofing checklist.
