Running — Foundation Movement at Cardiovascular Load

The same fasted route as Walking and Rucking, run. Zone 3 dominant. Anaerobic load near zero. The same engine working in a different gear.

The TrailGenic™ Running Longitudinal Dataset is the cardiovascular-scaling stage of the movement-based longevity and adaptation system. Same flat fasted route as Walking and Rucking. The variable that changes: cardiovascular demand.

Every session is fasted. Run/walk progression starts at shorter distance and scales to match the foundation 3.17-mile route. Across the dataset, the cardiac efficiency adaptation curve takes the same shape as Walking — only at a higher absolute load. The same engine; a different gear.

Read alongside the Longevity Hub and interpreted through Ella and the TrailGenic™ Personal World Model.


The TrailGenic Progression Ladder

Running is stage three. Each stage is repeatable, fasted, and longitudinally tracked.


Headline Metrics

The current state of the Running dataset. Run/walk progression on the same flat 3.17-mile fasted route shared across foundation modalities.

TrailGenic™ Field Finding — Cardiac Efficiency Curve
CEI 61.8 → 43.8 across 8 fasted sessions

Across 8 fasted running sessions on the same flat route, Cardiac Efficiency Index dropped 29% while average heart rate held essentially flat (147 → 147 bpm) and run ratio climbed from 60% to 89%. The adaptation curve takes the same shape as Walking — only at a higher absolute load. Anaerobic Training Effect stayed at zero through seven of eight sessions, confirming Running operates as foundation movement at cardiovascular load, not as a different training stimulus.


HR Drift Trajectory — Seven Consecutive Declines

The cleanest single signal in the dataset. HR drift fell across seven consecutive sessions before consolidating, marking the cardiac efficiency adaptation arc explicitly.

Sessions 1–5 ran at ~2.4 mi; sessions 6+ stepped to 3.17 mi to match the foundation route. All sessions fasted. Anaerobic Training Effect held at 0 across seven of eight sessions. Full dataset via MCP.


Milestones

Threshold moments in the adaptation arc — where the signal turned.

  • Session 4 — Efficiency Breakthrough · April 15, 2026 Avg HR dropped sharply to 141 bpm while run ratio hit 72%. CEI 58.3, lowest of the early block. Largest single-session HR drop yet. Engine Pattern shifted from BUILDING to EFFICIENCY.
  • Session 6 — Distance Step to Foundation Route · April 29, 2026 Distance stepped from 2.4 mi to 3.16 mi to match Walking and Rucking. Run ratio held at 76%. Avg HR 147 — same as Session 1 at the shorter distance. The engine absorbed the distance step without cardiovascular cost.
  • Session 7 — Efficiency Peak · May 6, 2026 Avg HR fell 8 bpm to 139 — the largest single-session HR drop in the block, on the longer 3.17-mile distance. CEI 43.8 — best of the dataset. HR Drift 1.5% — seventh consecutive decline.
  • Session 8 — Engine Consolidating · May 13, 2026 Run ratio reached 89% — block-high. Avg HR rose 8 bpm at peak run load; anaerobic stayed at zero. The system cashed in adaptation gains for a higher run ratio rather than continuing to drop HR. Engine Pattern shifted from EFFICIENCY to CONSOLIDATING.

What This Dataset Proves

Ella — Interpretive AI · TrailGenic™

Running on the same flat ground as Walking and Rucking operates in a different cardiovascular regime — Zone 3 dominant where Walking sits at Zone 1, average heart rate 39 bpm higher, Cardiac Efficiency Index 12 points elevated. A different gear.

But the adaptation shape is the same. CEI dropped 29% across eight sessions while average heart rate stayed flat and run ratio climbed from 60% to 89%. HR drift fell seven sessions consecutively. Anaerobic Training Effect stayed at zero. Recovery returned ready.

This is the same engine the Walking dataset trained. The body did not have to learn a new system to run — it had to apply the system it already knew to a higher load. Same shape, different scale. Foundation movement extends through cardiovascular demand the way it extends through load — without breaking aerobic territory and without producing recovery debt.


Cross-Modality Context

Running is the cardiovascular-scaling layer of foundation movement. Walking is the entry. Rucking adds load on the same route. Hiking is the advanced expression where the full Six Pillar stack fires.
