Living with Type 1 Diabetes and redefining what’s possible
Living with Type 1 Diabetes doesn’t mean giving up on big goals, it just means learning how to manage Type 1 diabetes in a different way.
In this episode of my podcast, The Long View: Living with Type 1 Diabetes, I speak to Marcus Davies about his journey from a life-changing diagnosis to completing an Ironman.
If you’re looking for a motivating and honest diabetes podcast about fitness, resilience and real-life management, this episode shows what’s possible.
A sudden and life-changing diagnosis
One of the most challenging parts of living with Type 1 Diabetes is how suddenly it can appear. Marcus’s diagnosis followed a serious accident, after which he experienced:
- Extreme tiredness
- Rapid weight loss
- Constant thirst
A few weeks after his accident, he was rushed to hospital and diagnosed with Type 1 Diabetes, with critically high blood glucose levels. Like many people, the diagnosis was overwhelming and unexpected, completely changing the direction of his life.
How to manage Type 1 Diabetes after diagnosis
Learning how to manage Type 1 diabetes can feel overwhelming at the start. Marcus describes being discharged with minimal guidance, having to quickly figure out:
- How insulin works
- How food affects blood sugar
- How to avoid highs and lows
This early stage is something many people struggle with. It’s not just a physical adjustment, it’s a complete mental shift in how you approach daily life.
Living with Type 1 Diabetes and staying active
For people who are used to being active, a diagnosis can feel like a major setback. Marcus had always lived an active lifestyle, but after diagnosis, he had to relearn how to exercise safely while managing Type 1 Diabetes.
This included:
- Monitoring blood glucose before, during and after exercise
- Adjusting insulin doses
- Planning nutrition carefully
It’s a powerful example of how living with Type 1 diabetes doesn’t stop you being active—it just requires more planning.
But rather than stepping back, Marcus chose to push forward. Drawing on his background in the military, he became a personal trainer and started setting ambitious goals. His journey shows how learning how to manage Type 1 Diabetes effectively can open new opportunities, not close them.
His first major challenge was a 108-mile cycle and that proved to him that he could still perform at a high level.
How to manage Type 1 Diabetes during endurance events
Endurance sport adds another layer of complexity to Type 1 Diabetes management. But that didn’t put Marcus off and he started to train to compete in Half Ironman events. A Half Ironman is a 1.2 mile swim, a 56 mile bike ride followed by a half marathon run.
To prepare for this Marcus had to:
- Carefully adjust his insulin levels before activity
- Plan his carbohydrate intake throughout the race
- Monitor his glucose levels as closely as possible
During the swim, he had to rely entirely on preparation. On the bike and run, he used a mix of energy gels and high-calorie foods to maintain stable blood sugar levels.
Completing an Ironman is a huge achievement for anyone, but doing it while living with Type 1 diabetes requires even more resilience.
Through planning, experimentation and determination, Marcus successfully completed the challenge, proving that diabetes doesn’t define your limits.
His story is a powerful reminder that with the right approach, it’s possible to achieve extraordinary things.
The importance of community in living with Type 1 Diabetes
One of the most valuable parts of living with Type 1 diabetes is connecting with others who understand it.
Marcus talks about the importance of community, what he calls “diabetic warriors”, and how support and shared experience can make a huge difference.
Through his work as a personal trainer, he now helps others learn how to manage Type 1 diabetes, especially in fitness environments.
