Endurance Lab OCR Preparation
Nine-week Level 3 preparation for a chosen 3–8-mile obstacle course event. Start with an established five-run week, recent running volume around 4–5 hours weekly, a comfortable 75–90-minute easy run or run/walk, and familiar strength movements. This advanced plan is not a couch-to-OCR programme.
Structure and progression
Weeks 1–8: five runs, two strength sessions, Monday and Thursday rest. Tuesday has controlled faster work; Friday has moderate steady work in build weeks and easy running in weeks 3, 6 and 8. Other runs stay easy. Wednesday and Friday strength also add fatigue: reduce or omit lifting when soreness affects running. On Friday, run first and separate sessions by several hours where possible. Weeks 3 and 6 reduce volume; week 8 tapers running and strength. Week 9 has two short runs, optional easy Friday running, rest and Saturday’s event, with no strength.
Weekly training time: W1 5:39; W2 6:10; W3 4:32; W4 6:15; W5 6:22; W6 4:37; W7 6:41; W8 4:02; W9 1:08 plus the event, or 0:53 without optional Friday. Times include warm-ups, full recoveries and cooldowns. Timed long runs progress from 85 to 110 minutes with recovery reductions. Steep, technical or upper-distance events may need a stronger existing time-on-feet and terrain base; match the plan to expected event duration. Saturday’s short run is optional when fatigued.
Intensity
Use current, validated running lactate-threshold HR (LTHR), not maximum HR or cycling LTHR. Aerobic builders use full Z1/Z2 bands relative to running LTHR. Z2 stays conversational at RPE 2–3/10. Short controlled efforts use RPE 6–7/10; moderate steady blocks use RPE 4–5/10 with short phrases possible. Both include easy recoveries. HR is secondary for these efforts: do not chase a lagging HR. Terrain, footing, heat and fatigue take priority; slow down, walk climbs or use run/walk.
Strength and obstacles
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 failure sets. Equipment: low stable step, clear carry lane and suitable weights or bands. Seek qualified instruction for unfamiliar lifting or obstacles. General strength and grip do not replace supervised obstacle practice or guarantee completion.
Using the plan
Every calendar entry includes the original Endurance Lab RPE and Training Zones PDFs, instructions and scaling guidance. Running sessions are structured; strength, rest, planning and race entries use written instructions. Device support for RPE/ranges varies. Stale TSS/IF estimates were cleared; blank or zero planned TSS does not mean zero stress. Race duration is not preset. This general plan does not include individual monitoring or coaching contact.
Shorten or omit sessions with poor recovery; do not add missed hard work. Stop if pain changes your stride and seek appropriate assessment for persistent or worsening symptoms. Follow the organiser’s current course and safety briefing. These adjustments cannot guarantee freedom from injury.
