GORUCK Event Readiness Estimator

How the Score Works

Four things go into the score: distance, pack weight, how often you ruck, and how much time you have left to train. Each is rated against the typical demands of the event you pick. Distance gets the most weight because it's the slowest thing to build. Pack weight comes next. How often you train and how much time you have shape what's actually possible in the weeks you have left.

A score of 86 or higher means you already meet or beat every baseline. At that point you should be protecting recovery and locking in your event-day plan, not piling on more training. 66 to 85 is Conditioned, where one or two things need tightening up but the foundation is there. 40 to 65 is Building, which is doable in a normal prep window if you stay consistent. Under 40 means the gap is big enough that you should push the event back or pick a shorter one.

What the Event Targets Are

These match what experienced ruckers report, not GORUCK's official scoring. Light assumes about 9 miles at 20 lbs over roughly 5 hours. Tough assumes about 18 miles at 30 lbs across 10 hours. Heavy assumes 40+ miles at 40 lbs over 24 hours. Real events vary by cadre and location. Use the score to plan, not to predict.

What "Time Left" Means

Time Left is how much of the recommended prep window you actually have. A Heavy event needs about 16 weeks. A Light can fit in 8. If your Time Left sub-score is low, the rest of the math gets harder. You can't cram event prep. The 10 percent rule (only add 10 percent to your long ruck distance each week) limits how fast you can build. A short timeline plus a big gap is the most common reason ruckers don't finish.

What This Tool Won't Tell You

It can't tell you whether your knees, hips, or feet are ready. For that, use the Injury Risk Assessment. It doesn't calculate your event-day pace either. Use the Pace Calculator for that. And it doesn't account for terrain, elevation, or cadre style, which can shift difficulty a lot.
