Short answer
Not a single studyNo clear answer.
The article covers a research area rather than reporting a specific new paper, so there is no single study to check it against.
Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.

Claim 1 of 6Not checkedNew research to be presented at the Annual Meeting of the European Association for the Study of Diabetes shows that, with the use of continuous glucose monitoring devices, people with type 1 diabetes can complete a marathon safely and achieve finishing times similar to runners without diabetes.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 2 of 6Not checkedThe study was conducted by Michał Kulecki, Dr. Andrzej Gawrecki and colleagues at Poznan University of Medical Sciences and Raszeja City Hospital in Poznan, Poland, and assessed glucose levels, carbohydrate intake and CGM accuracy during the 2025 Poznań Marathon.View evidenceHide evidence
As stated2025 Poznań Marathon; 42-km race
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 3 of 6Not checkedThe observational study included 20 amateur runners: 10 with type 1 diabetes and 10 controls without diabetes, and for the T1D group marathon performance did not differ significantly between groups, with completion times of 228 minutes versus 248 minutes for controls.View evidenceHide evidence
As stated20 runners; 228 minutes vs 248 minutes
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 4 of 6Not checkedDuring the race, the runners with type 1 diabetes consumed a median of 53.5 g of carbohydrate per hour, and two hypoglycemic measurements occurred in the same participant, who nevertheless completed the race.View evidenceHide evidence
As stated53.5 g/hour
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 5 of 6Not checkedCGM accuracy was reduced during the marathon, with intermittent and real-time systems differing from glucometer measurements by about 43% and 37% on average, respectively, and overestimating capillary glucose.View evidenceHide evidence
As statedapproximately 43% and 37%
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 6 of 6Not checkedThe authors say that runners with type 1 diabetes preparing for longer endurance events should consider checking glucose with a glucometer, especially when sensor readings do not match how they feel, and should discuss an individualized glucose, carbohydrate and hydration plan with their doctors before the event.View evidenceHide evidence
