How to Avoid Failing Obstacles During OCR Races
Obstacle failure in OCR almost always comes down to three categories: technique under fatigue, pacing errors, and skill gaps. This guide walks through each, with the diagnostic question that tells you which one is killing your races.
The diagnostic question After your last race, ask yourself: did I fail an obstacle I had completed in training that morning? If yes, it's a fatigue/pacing issue. If no, it's a skill gap.
Category 1: Fatigue failure You can do the obstacle fresh but not at mile 4. - **Fix 1:** Add fatigued obstacle training. Run 800m, then attempt the obstacle. - **Fix 2:** Pace earlier miles slower. - **Fix 3:** Take 10 seconds before the obstacle to slow your breathing.
Category 2: Pacing error You arrived at the obstacle too gassed because you raced the first 2km. - **Fix:** Run the first km at conversational effort. Walk steep climbs.
Category 3: Skill gap You can't do the obstacle even fresh. - **Fix:** Add weekly skill work specifically for that obstacle. See our [skill drill articles](/blog).
High-failure obstacles and their fixes | Obstacle | Top failure | Fix | |----------|-------------|-----| | Monkey bars | Grip blowup | Fatigued bar training | | Spear throw | Bad release | Daily 10-throw practice | | Rope climb | Bad foot lock | J-hook drilling | | Multi-rig | Pump out | Mixed-grip endurance | | Z-walls | Foot slip | Slow lateral traverse |
Race-strategy rules 1. Walk every uphill in the first half. 2. Chalk before every grip obstacle. 3. Skip and burpee if grip is gone — failure mid-rig wastes more time. 4. Eat or gel every 45 minutes.
Beginner, intermediate, advanced - **Beginner:** Focus on burpee fitness — you'll need them. - **Intermediate:** Eliminate fatigue failures via mixed-modal training. - **Advanced:** Optimize transitions and pacing for top-10 finishes.

Frequently Asked Questions
Are burpees ever the right strategy?
Yes — if grip is gone, 30 burpees may be faster than a 50% chance of mid-rig failure plus burpees.
How do I train fatigued obstacle work safely?
Use lower obstacles (low monkey bars, low rigs) so a slip is a small fall, not a serious one.
Should I taper before a race?
Yes — 5–7 days reduced volume produces measurable grip and run improvements.
