Endurance Lab OCR Preparation
A nine-week Level 1 plan for a chosen 3–8-mile obstacle course event, combining aerobic running, controlled faster work and basic strength. Enter with an established four-run-per-week base, a comfortable 40-minute easy run or run/walk, and familiarity with the prescribed strength movements. This is not a couch-to-OCR plan.
Weekly structure and progression
Weeks 1–8 contain four runs and two strength sessions. Tuesday is the only faster run; Thursday, Friday and Sunday stay easy. Strength also contributes fatigue: reduce Wednesday's dose if Tuesday leaves soreness. Recovery volume falls in weeks 3 and 6. Week 8 tapers running and strength; week 9 has two short runs, Friday rest and Saturday's event.
Planned weekly training time: week 1 3:47; week 2 4:03; week 3 3:10; week 4 4:25; week 5 4:45; week 6 3:30; week 7 4:55; week 8 2:50; week 9 0:48 plus the event. These times include prescribed session recoveries, warm-ups and cooldowns. The longest easy run is 75 minutes. Upper-distance, steep or technical events may require a stronger existing time-on-feet and terrain base; select a plan suited to your expected event duration.
Pace and perceived exertion
Use a current, validated running threshold pace in TrainingPeaks. Aerobic running uses full Z1 and Z2 bands based on threshold speed: higher builder percentages mean faster running, not a longer min/km time. Keep Z2 conversational at RPE 2–3/10. Short controlled efforts use RPE 6–7/10 with easy recoveries, never mandatory maximal effort. Terrain, footing, heat and fatigue take priority over pace: slow down, walk climbs or use run/walk as needed.
Strength and obstacle preparation
Use familiar loads, controlled technique, full rests and 3–4 good repetitions in reserve. Recovery weeks reduce sets; taper strength is light maintenance at RPE 3–4/10. No maximum testing or sets to failure. You need a low stable step, safe carry lane and suitable weights or bands. Seek qualified instruction for unfamiliar lifting or obstacles. General strength and grip work do not replace supervised obstacle technique or guarantee obstacle completion.
Using the plan
Every calendar entry includes the original Endurance Lab RPE and Training Zones reference PDFs, alongside session instructions and scaling guidance. Running workouts are structured; strength, rest, planning and race entries use written instructions. Device support for RPE and ranges varies. Stale planned TSS and IF estimates were cleared; a zero or blank planned TSS display does not mean zero training stress. Race duration is not preset. This general plan does not include individual monitoring or coaching contact.
Shorten or omit sessions when recovery is poor; do not add missed hard work. Stop when pain changes your stride and seek appropriate assessment for persistent or worsening symptoms. Follow the organiser's current course and safety briefing. Adjustments reduce avoidable load conflicts but cannot guarantee freedom from injury.
