Workout library
The sessions you repeat
You don’t need 50 workouts. You need a small library that you execute consistently, then progress safely.
Time-on-feet long session
Purpose: Build durable endurance without over-focusing on pace.
Prescription: 90–180+ minutes easy. Include hiking on climbs if terrain demands it.
Substitutions
- • Split into two sessions on high-stress weeks; keep total time similar.
Red flags
- • Sharp pain that changes form.
- • Needing multiple days to recover every week.
Back-to-back long sessions (scaled)
Purpose: Train durability and pacing under accumulated fatigue.
Prescription: Two consecutive days: long easy + medium easy. Keep both controlled and finish feeling stable.
Substitutions
- • If injury-prone: one long run + one long hike.
Red flags
- • Turning day 2 into a race.
- • Fatigue that spills into the entire next week.
Hills (controlled) + hiking practice
Purpose: Build climbing efficiency and downhill resilience safely.
Prescription: 6–12 × 2–4 min uphill at controlled effort; hike steep reps. Jog easy down.
Substitutions
- • Stair climbing or incline treadmill if needed.
Red flags
- • Knee pain on descents.
- • Over-striding downhill.
Cutoff pacing rehearsal
Purpose: Practice pacing that keeps you safe against cutoffs without burning matches.
Prescription: 60–120 min with segments at your cutoff-safe effort. Practice aid-station efficiency (quick in/out).
Substitutions
- • Do it as a hike-run combo on trails.
Red flags
- • Chasing pace on terrain that demands hiking.
- • Skipping fueling while ‘testing’ pace.
Fueling practice (GI-friendly)
Purpose: Train your gut and reduce race-day surprises.
Prescription: On long sessions: practice a simple schedule and adjust products if GI issues appear.
Substitutions
- • Lower intensity + smaller doses if tolerance is low.
Red flags
- • Repeated GI distress without changes.
- • Ignoring hydration in heat.
Strength durability (lower-body + trunk)
Purpose: Support downhill resilience and long-duration posture.
Prescription: 2×/week, 25–40 min: single-leg, posterior chain, calves, trunk. Avoid soreness spikes.
Substitutions
- • Travel circuit with step-ups, calf raises, core.
Red flags
- • DOMS ruining long sessions.
- • Sharp joint pain.
Adaptation rules
What to do when life happens
Most training failures are not fitness failures — they’re pacing, sleep, or scheduling failures. Use simple rules.
Missed workout
- • Protect the long session; drop extra intensity.
- • Don’t stack back-to-backs to ‘catch up’.
Low sleep week
- • Keep it easy; reduce long-session duration by 15–25%.
- • Replace hills with hiking if needed.
Fatigue signals
- • If legs feel dead, replace with easy hike and mobility.
- • Prioritize fueling and sleep; treat it like a cutback week.
Pain or injury
- • Pain that changes gait is a stop signal.
- • Swap to hiking/biking until pain-free; return gradually.
Travel week
- • Short sessions win: keep one long hike/run and one hills touch if possible.
- • Use time-based training and stay consistent.

Evidence (high level)
Why this structure works
- • Ultras reward time-on-feet and durability, not heroic pace sessions.
- • Back-to-back sessions train fatigue resistance safely when scaled.
- • Cutoff planning is a pacing skill; train it like a discipline.
- • Fueling and hydration are part of the training plan, not a race-week afterthought.
FAQs
Should I train by pace or time?
For ultras, time-on-feet is usually more useful than pace. Terrain changes pace; effort and durability are what transfer.
Do I need back-to-back long runs?
They can help, but they must be scaled and recovery-aware. If you’re injury-prone, use one long run and one long hike.
How do I prepare for cutoffs?
Use cutoff-safe effort in training, practice aid-station efficiency, and build margin for terrain and fatigue.
How much elevation training do I need?
Match the race demands. If the race is hilly, you need hills. If it’s flat, you still need durability.
How do I avoid GI issues?
Practice fueling early and often in long sessions. Adjust products and timing; don’t wait for race week.
What’s the biggest mistake?
Turning long sessions into races. Ultras reward staying consistent week after week.
