Debugging My Kona: Heat, a Concussion and My Longest IRONMAN Ever
Nine weeks after a crash and a traumatic brain injury, Jill raced the 2026 IRONMAN World Championship in Kona and finished in 13:14, more than an hour slower than 2025. In this solo episode she debugs her own race: a forgotten bottle, rough swells, calf sleeves that wouldn't go on, a bike where her heart rate never followed her power, and the pitcher of ice at mile 70 that saved her day.
Jill expected somewhere between 10:40 and 11:40 at Kona this year. She finished in 13:14. In this episode she treats herself like any athlete she coaches, going back through the data to separate the conditions, the mistakes and the residual effects of an August 8 crash that totaled her bike and left her with a concussion.
In this episode:
- The August crash: a tubeless tire coming off a hookless rim at nearly 50 mph, the injuries, and a compressed return to training
- Why she pulled out of the 70.3 World Championship in Nice to focus on Kona
- Race morning: the corral water bottle that ended up in the checked bag
- The swim: mixed men's and women's start waves, the five sections of the course, and 6–12 foot swells
- T1: a crowded shared tent, a missing face shield and three minutes lost to calf sleeves that wouldn't go over wet feet
- The bike: power in high zone 3 and low zone 4 while heart rate stayed in zone 2, and why that gap isn't sustainable
- Mile 70: putting her feet down and the pitcher of ice that changed the next ten miles
- Mile 90: flagging down a course marshal for an ice-cold bottle of water
- Wind on the Queen K and to Hawi, and the "slowness penalty" for later bike starters
- Heat strain vs. hyponatremia vs. too many electrolytes, and what her sweat testing says
- What to watch for on a hot race: sweat on your forearms, whether you're peeing on the bike, and signs of confusion
- The run: humidity on Ali'i Drive, the Palani climb, the Queen K "air conditioning," the Energy Lab after sunset and a surprise sprint at the finish line
- Racing after a concussion: what she expected, what she didn't account for, and giving yourself grace
