Abstract:
Ultramarathon with Type 1 Diabetes Abstract. We report the case of a 63-year-old runner with type 1 diabetes mellitus requiring insulin since the age of 21. At the age of 32, he ran his first marathon, and at the age of 34 the first ultramarathon. So far, he has finished more than 90 marathons and ultramarathons. Thanks to an insulin pump and continuous glucose monitoring, he has so far completed 48 24-h-runs with an average distance of 133 km. The analysis of running volume and HbA1c values showed a significant increase in monthly exercise volume, a significant decrease in HbA1c values over the years, and a significant correlation between monthly running kilometers and HbA1c values.
