Training Rules

8 rules (6 hard, 2 soft)

Evidence-based constraints that guide workout generation. Hard rules are never broken; soft rules can be adjusted for experienced athletes.

Volume

Soft

Single long run should not exceed 5 hours (quality over extreme duration)

Diminishing returns beyond 4-5 hours; risk of injury increases

Exception: Race simulation runs in final build phase

Hard

Back-to-back long runs: Saturday long (3-4h) + Sunday medium (2h)

Trains running on tired legs without single-session extremes

Hard

Weekly elevation gain increase should not exceed 20%

Eccentric stress from climbing/descending requires adaptation

Exception: Returning from flat terrain phase

Recovery

Hard

Cutback week (30-40% volume reduction) every 3rd week

Ultra training volume requires more frequent recovery

Hard

No intensity work for 72 hours after back-to-back weekend

Back-to-back creates significant fatigue requiring full recovery

Hard

Heavy downhill sessions (>1000m descent) limited to every 2 weeks

Eccentric damage from downhills requires extended recovery

Safety

Hard

Long runs over 2 hours must include fueling practice

Race-day fueling is a skill that must be practiced in training

Exception: Fasted adaptation runs (experienced athletes only)

Intensity

Soft

Night runs limited to 1-2 per month during build phase

Night running adds stress; reserve for race-specific preparation

Exception: Final 6 weeks before 100-mile race
