James Norton celebrated completing his first London Marathon by displaying his glucose monitor and insulin pump, while posing alongside his rarely seen parents. The 40-year-old actor raised an impressive £132,000 for Breakthrough T1D, a charity supporting type 1 diabetes research and care.

Marathon Achievement Amid Challenges

Norton crossed the finish line in 4 hours and 29 minutes, despite battling a chest infection that intensified the 26.2-mile ordeal. He described the event as a “mad and beautiful experience,” crediting crowd support for carrying him through.

On Instagram, Norton shared photos of himself proudly holding his medal with his beaming parents and a touching image showing his glucose monitor to six-year-old Emma, a fellow type 1 diabetic diagnosed at age two. “Did it. Just,” he posted. “Had a chest infection which made it pretty gruelling, but the incredible support from the crowds carried me to the finish line.”

He thanked donors, noting contributions from the Bukhman Foundation pushed totals to £132,000. “This money will go towards supporting young diabetics across the country, but also each pound raised gets us closer to the cure that all of us Type 1 Diabetics so desperately want,” Norton wrote, mentioning his mother, sister, and Emma.

Norton relies on a Dexcom G7 monitor and Omnipod 5 pump, worn 24/7, which proved vital during the race to maintain safe glucose levels.

A Family Affair with Type 1 Diabetes

Diagnosed at 22 after symptoms like weight loss, frequent urination, and fatigue, Norton views his condition as a “mini-superpower” fostering empathy. His mother and sister also live with type 1 diabetes, an autoimmune disease where the body fails to produce insulin, requiring daily injections to manage high blood glucose.

The family shares Dexcom devices, leading to lighthearted moments at the dinner table when alerts sound. “Can you imagine at the kitchen table? When it goes off, we’re like, ‘Who is it?’ We all grab our phones,” he joked.

High-Profile Hypo Incident

Last year at the GQ Men of the Year Awards, Norton’s blood sugar crashed after insulin dosing for an expected carb-heavy meal. Served a low-carb “fashion dinner,” he sweated profusely opposite Nicole Kidman. “I was dripping with sweat,” he recalled on the Off Menu podcast.

He discreetly sought orange juice from a waiter, sparking chaos. A Pret chocolate bar and steaming potatoes arrived mid-Jude Law’s speech. “Everyone down the table is going, ‘Why are you…?’ I just looked like a potato-loving glutton,” Norton said.

Tech Transforming Daily Life

Continuous glucose monitors (CGM) like Dexcom have revolutionized Norton’s management, preventing severe overnight hypos that left him panicked and disoriented. “Now, way before that happens, we get a beep,” he explained. “You cannot underestimate how much difference Dexcom gives you in your life. It’s huge.”

The devices enable swimming, running, and acting without limitation, though concealing them during nude scenes poses challenges. In the 2023 play A Little Life, he covered the sensor with skin-colored bandages alongside his microphone pack, dubbed his “puck.”

Theater and Adrenaline Struggles

Adrenaline from performances disrupts glucose, prompting Norton to stitch sugar tablet pockets into period costumes. During Journey’s End in 2011, shaking from low sugar led co-stars to improvise aid with Lucozade in a teacup. “Pandemonium broke loose,” he recalled.

Low glucose triggers anxiety and “existential dread” for Norton, but technology and awareness empower his advocacy for fellow type 1 diabetics. “Love to all my fellow T1D warriors out there. We got this,” he posted.
