Last Update:
The fasted marathon is not a single event; it is the outcome of months of controlled metabolic and mental training. Weekly running distance and fasting hours are controlled in deliberate steps to see how endurance and metabolic stress interact. The data above shows changes as race day approaches.
Key events such as the 36-hour fasted half-marathon and the 48-hour metabolic shift are marked to track performance after deeper fasting cycles.
Recovery and Autonomic Signals
Measuring HRV and Resting Heart Rate Trends
Heart rate variability and resting heart rate are tracked daily through Fitbit to monitor how the nervous system responds to training and fasting.
Stable or improving HRV with a gradual decline in resting heart rate suggests adaptation, not overload. Sharp drops or unexplained spikes trigger changes in fasting windows, training intensity, or sleep priorities.
Sleep and Readiness
- Total sleep: 6 h 30 min
- Deep sleep: 1 h 25 min
- REM sleep: 1 h 16 min
- Light sleep: 3 h 49 min
Average for last 14 days
Sleep duration and timing are recorded every night.
The goal is not perfection, but enough deep and REM sleep to support decision-making, training, and travel.
If sleep quality or duration falls for several days, the protocol shifts toward recovery, not additional stress.
Key Milestones in the Fasted Marathon Build-Up
Each major effort in this journey functions as a checkpoint — a way to test whether the system is ready to progress.

Fat Blaster
The structured starting point focused on insulin resistance, appetite control, and stable energy before heavier training began.
48-Hour Fast – Metabolic Shift
A controlled observation of the transition from glucose dependence to fat-based metabolism, logged with continuous metrics.
Fasted Half Marathon – 36-Hour Fast
Half-marathon performance after a prolonged fast, testing whether pace and recovery hold under low fuel conditions.
Key Long Runs
Progressively longer fasted runs — 10km, 20 km, 25 km, 30 km — each logged with heart rate, perceived effort, and recovery markers.
Prep Races
Testing grounds for the real deal. These races serve to set the tone for the true race.
Fasted Marathon Project
The final phase where fasting cycles, training load, and recovery are aligned for one objective: completing a full marathon in a fasted state with composure and clarity.
Tools Powering This Experiment
Every metric on this page is generated by specific tools and protocols. This is the current stack.
- All
- Wearables
- Metabolic
- Documentation
- Future Partners
FitBit
Daily tracking of heart rate variability, resting heart rate, sleep stages, and overall movement. These signals guide when to push and when to step back.
Unicity
Structured metabolic support and supplementation to address insulin resistance, stabilize energy, and prepare for deeper fasting experiments.
Strava
External record of distance, pace, terrain, and elevation. Strava provides the context for how often, how far, and how fast the system is moving.
Future Performance Partner
Reserved slot for a founding partner in recovery, analytics, or performance technology — integrated directly into the next phase of this experiment.
Receive the Fasted Marathon Brief
When something meaningful happens in this experiment — a major long run, a new fasting protocol, or race-day results — I document it in a concise brief. No daily noise, just structured updates and what the data suggests for long-term performance and health.
Integrate Your Technology or Brand
If your brand develops tools for metabolic health, wearables, recovery, or executive performance, this fasted marathon project is a live testbed. Protocols are pre-planned, data is collected consistently, and results are published openly.
Partners can position their products inside a real-world executive experiment — not a controlled lab or one-off campaign.
