Ultramarathon with Type 1 Diabetes We report on the case of a 63-year-old runner with diabetes mellitus type 1, which has been needed since its 21st year of life. At the age of 32, he completed his first marathon and the first ultramarathon at the age of 34. So far, he has completed more than 90 marathons and ultramarathons. Thanks to an insulin pump and continuous blood glucose measurement, he has previously completed 48 24-hour runs with an average distance of 133 km.
The analysis of the running volume and HBA1C values showed a significant increase in the monthly training volume, a significant decrease in HBA1C values over the years and a significant correlation between the running kilometers and the HBA1C values.
