An inspiring Scot completed the Edinburgh Marathon<\/a> while vlogging about the challenges of a chronic illness.<\/p>\n Callum, who has type one diabetes, completed the marathon <\/a>on Sunday. He was diagnosed with the condition after he drastically began losing weight and his eyesight “fell off a cliff”.<\/p>\n The influencer shared his story on TikTok<\/a>, saying: “But here I am today – the fittest I’ve ever been, probably the healthiest I’ve ever been aside from having type one diabetes.” Type one diabetes is a condition where the body cannot produce insulin, the hormone which breaks down sugar to use as energy.<\/p>\n Edinburgh Live<\/a> reports that as a result, blood sugar levels become too high in the blood and lead to complications.<\/p>\n Throughout his impressive four-hour marathon race<\/a>, his blood sugar ranged from low to high – showcasing the daily ups-and-downs that come with living with type one diabetes.<\/p>\n For healthy individuals, normal fasting blood sugar levels are between 4.0 to 5.4 mmol\/L, and up to 7.8 mmol\/L two hours after eating, according to Diabetes <\/a>UK.<\/p>\n Callum’s ranged from 11.1 mmol<\/a>\/L to much lower.<\/p>\n When Callum was 33km into the race<\/a>, he shared an update when his blood sugar was at 4.5 mmol\/L.<\/p>\n He said: “Thirty-three kilometers in, blood sugar still dropping<\/a>, so I’m just going to walk for a bit to see if I can level this out because I’ve had so much sugar. Still not going up.”<\/p>\n He completed the race with a time of around four hours, saying: “That was tough<\/a>” upon crossing the finish line.<\/p>\n The video<\/a> garnered over 46,000 views in less than 24 hours.<\/p>\n Callum has previously posted on social media saying “Doing any type of long distance running<\/a> when you have type one diabetes can be pretty annoying due to the amount of extra stuff you have to bring.<\/p>\n “The main things to bring with you are a ton of emergency sugar and to make sure you’re carrying your insulin pen with you.”<\/p>\n He added in his post: “Edinburgh Marathon 2025<\/a> with my blood sugar levels throughout.<\/p>\n “I met a lot of other people <\/a>with type one diabetes as well as a lot of people raising money for it which is always amazing to see.<\/p>\n
