Continuous Glucose Monitoring

I have been on the waiting list for Stelos early access program and was pleasantly surprised to see an email pop into my inbox suggesting I could order one 🙂

I spent roughly 3 months collecting data, doing workouts, monitoring my blood glucose levels, but like many of my data focused gadgets, it ended in with some unique insights about my health, but also nothing ground breaking or earth shattering. I did use it during a 70.3 Race, lots of tough training sessions and I was hoping to identify some weaknesses and low points which would correlate with low energy or fatigue but that did not seem to materialize.

Ultimately what I am learning is that the human body is extremely complicated, there are a handful of reasons why we feel the way we do which we can measure, but probably millions of others, which we can’t. It always seems to bring me back to the mantra of “Correlation does not equal causation”.

These devices do an excellent job at identifying spikes, the highs, and the actual blood glucose level, but in a training/exercises physiology context, they don’t take into account heat, exhaustion, previous exercise, load, hydration, electrolyte levels, and so on. Ultimately what we as endurance athletes need in order to identify causation is all of these characteristics and metrics available in a single tool, in real time, and correlated 😉
