Challenge Format: 10 consecutive days x (swim 3.8 km + bike 180 km + run 42.2 km)

Date and Place: August 2 – 11, 2024 | Estonia

Goal: My time goal was to complete a full Ironman triathlon every day for 10 consecutive days with a total time under 100 hours. I successfully achieved this. Ideally, I aimed to finish each day in under 10 hours. For the first 7 days, I managed this well and did my best to keep the times below 10 hours for the last 3 days as well, but times slightly exceeded my target. On the eighth day, my final time was 10:01:16 — I forgot to place my cycling jersey in the first transition area, costing me about 1.5 minutes to retrieve it, which disrupted my rhythm. Without this mishap, the 10-hour mark could have been attainable even on the eighth day — but with such a long event, these things happen. Given that I couldn’t beat the 10-hour mark on the final two days due to challenging weather conditions, I didn’t feel disappointed about day eight.

About the Course: I completed the course on the same routes each day.

Swimming: Conducted in a 25-meter indoor pool, requiring 152 laps each day. Start time was 7:00 AM daily.

Cycling: Each cycling lap measured 5,847 meters, which I completed 31 times daily (181.257 km). The course was officially measured by an individual certified by World Athletics/AIMS.

Running: Each running lap was 1,455.3 meters, repeated 29 times daily (42.204 km). The course was also officially measured by a World Athletics/AIMS-certified measurer.

Weather: Once again, the saying “weather is the fourth discipline in ultratriathlon” proved true. Over the 10 days, conditions were highly variable. Most days had showers and strong winds, with heavy thunderstorms on the last two days. The wet, cold, and windy weather significantly affected my performance in the final three days.

Result: 99 hours 49 minutes 47 seconds (new world record).
