GORUCK Heavy Training Plan
12-week preparation for the 24-hour pinnacle Challenge
GORUCK Event Prep · 13 minutes read
Event Overview
The GORUCK Heavy is the pinnacle of the GORUCK Challenge series. It runs 24+ hours, covers at least 35 miles of movement, and starts with a PT test that has ended events before they began. There is no sleep, no scheduled rest, and no shortcut to finishing. The patch you earn at the end has never been for sale and never will be.
Here's how it goes. You show up at the start point with a class of 15 to 30 strangers. A Cadre, almost always a former Special Forces operator, takes attendance. The Welcome Party starts immediately. 2 minutes of push-ups. 2 minutes of sit-ups. Standards based on the Army Physical Fitness Test. Anyone who fails to hit the 60% mark gets dropped or punishes the class. Then the 12-mile road march begins. Your team has 3 hours and 30 minutes to finish it together. Slower than that and the class starts over.
After the road march, the real event begins. The next 18 to 22 hours are a continuous test of team coordination, problem-solving, and willingness to keep moving when every muscle has decided to quit. The Cadre run team-weight movements, surprise PT, water crossings, log carries, and long ruck movements that go on longer than feels possible. The class carries a sandbag or team weight at all times. There's an American flag that never touches the ground. People throw up. People cry. Some people quit. The ones who finish do so because the rest of the class refused to let them stop.
GORUCK's own event description is unambiguous: this should not be your first GORUCK event. The Heavy assumes you have already finished a Tough, ideally more than one, and that you understand what Cadre standards feel like under load. If you haven't finished a Tough yet, build that base first through the event prep program and a Tough finish before attempting a Heavy.
Physical & Mental Prerequisites
Before you sign up, run an honest baseline check. The Heavy is not a goal event you reach for. It's an event you earn the right to attempt by being demonstrably ready.
Physical baselines you should already hit.
You can ruck 12 miles with 35 pounds in under 3 hours. That's a 15-minute-per-mile pace under event weight and it's the floor, not the ceiling. If you can't hit this on a fresh day, you definitely can't hit it after a Welcome Party.
You can do at least 30 push-ups in 2 minutes and 40 sit-ups in 2 minutes with strict form. These are roughly Army PT 60% standards for the 30 to 35 age bracket. Older or younger brackets shift, but these are reasonable targets for most adults.
You can deadlift 1.5x your body weight and squat 1.25x your body weight. Heavy events involve picking up sandbags, logs, and teammates. A weak posterior chain is the fastest path to a rolled-out lower back at hour ten.
Mental baselines that matter more.
You have finished a GORUCK Tough or an equivalent 12+ hour event. You understand what Cadre time standards feel like under load. You have been awake and moving for at least 18 continuous hours without stopping in training. You have done one full overnight ruck where you started at 8 p.m. and finished at sunrise. Without these experiences, the Heavy will introduce you to a version of yourself you have not met yet, and that meeting is harder when you're also carrying a sandbag.
If you can't check all three physical and all four mental baselines, postpone the event by 90 days and use the time. The Heavy is harder to come back from than it is to wait for.
12-Week Training Timeline
This plan assumes you start week 1 already meeting the prerequisites above. Five sessions per week. Three rucks, two strength and PT days. The long ruck is on Saturday. Sunday is rest or active recovery. Cross-loading principle applies throughout: every long ruck should match or exceed event weight.
Weight column refers to dry pack weight. All paces are target average for the long ruck of that week.
| Week | Long Ruck | Weight | PT Focus | Block |
|---|---|---|---|---|
| 1 | 8 mi | 35 lb | Push-ups, sit-ups baseline | Foundation |
| 2 | 10 mi | 35 lb | Deadlifts, sandbag carries | Foundation |
| 3 | 12 mi timed | 35 lb | Mock AFPT test | Foundation |
| 4 | 8 mi | 35 lb | Active recovery, mobility | Deload |
| 5 | 14 mi | 40 lb | Buddy carries, log lifts | Volume |
| 6 | 16 mi | 40 lb | Team weight rotations | Volume |
| 7 | 18 mi | 40 lb | Full mock Welcome Party | Volume |
| 8 | 10 mi | 35 lb | Mobility focus | Deload |
| 9 | 20 mi | 40 lb | Sandbag + ruck mix | Peak |
| 10 | 22 mi overnight | 40 lb | Sleep deprivation training | Peak |
| 11 | 14 mi | 35 lb | Taper, gear lock-in | Taper |
| 12 | 6 mi easy | 35 lb | Rest, light PT only | Event week |
Three sessions in this plan matter more than the others. The week 3 12-mile timed ruck is your first real benchmark. If you can't finish it under 3:30 with 35 pounds, the rest of the plan needs to be paced lower. The week 7 mock Welcome Party is where you do a full simulation: max push-ups, max sit-ups, then the 12-miler with team weight. Treat it like event day. The week 10 overnight ruck is the only training session that prepares your brain for what continuous movement past midnight actually feels like. Skip it and you're betting on never having done it before.
If you're coming from a Tough finish and you want a longer ramp, stretch the foundation block from 3 weeks to 6 weeks before starting week 1 above. The Heavy rewards a deeper base. There is no reward for compressing the timeline.
Weight & Gear Standards
The official requirement is 35 pounds dry if you weigh 150 pounds or more, or 25 pounds dry if you weigh under 150. Dry means without water and without food. Cadre weigh your ruck at the start. They'll do it again later if they feel like it. Lose weight from your pack during the event and you'll do push-ups about it.
Pack the ruck plate first, against your back, sitting high. Frameless or low-quality rucks will destroy your shoulders inside the first 6 hours. The GORUCK GR1, GR2, and Rucker all work. Mystery Ranch and Eberlestock packs are also field-proven. Buy used if you have to. Don't cheap out here.
Beyond the plate, here's the working gear list:
Water. 3-liter bladder minimum, plus a 1-liter Nalgene as backup. You'll refill at any water source the Cadre allows.
Food. Pack 2,500 to 3,500 calories of portable food. Real food first: sandwiches, rice cakes, jerky, peanut butter packets. Energy gels and bars work, but don't make them your whole strategy because Cadre may confiscate them.
Clothing. Wool or synthetic base layer top and bottom. Weather-appropriate shell. A beanie or hat. Two extra pairs of merino wool socks taped together in a Ziploc. Cotton is forbidden, both by GORUCK and by physics.
Foot care kit. Leukotape, Body Glide, blister bandages, ibuprofen, scissors. Tape your feet before the event starts. Re-tape during any halt the Cadre give you.
Headlamp plus backup. Most Heavy events start late evening or morning and run through the night. Two light sources. Spare batteries.
Team gear. The class brings a 25 pound class weight (sometimes heavier) and an American flag. Coordinate who carries what in the days before the event so no one shows up without anything.
Team Coordination
The Heavy is not an individual event with other people present. It is a team event with individual suffering. Cadre fail classes for team breakdowns more often than for individual weakness. The people who finish are the people who learned to function as part of a unit, not as a fast person dragging slow people along.
Pre-event coordination. If your event roster is public, find your class on the GORUCK Sandlot chat or Facebook event page. Introduce yourself. Coordinate who's bringing the team weight, who's bringing the flag, who has medical training, and who's done a Heavy before. Show up with 5 names you already know.
Roles during the event. Heavy classes self-organize into rotating roles. Team Leader runs the count and relays Cadre instructions. Assistant Team Leader handles the team weight rotation. The Navigator carries the map and the compass. The Medic carries extra Leukotape and ibuprofen. The Logger keeps time for Cadre standards. These roles rotate. Everyone leads at some point. Everyone follows at some point.
Team-weight discipline. The class weight cannot touch the ground. Rotate it every 5 to 10 minutes. The strongest people in the class take it first when fatigue hits the rest of the group. Watching teammates struggle without offering to take the weight is the fastest way for a Cadre to lose respect for the class.
The communication standard. Loud, clear, and from the front of the formation. Cadre instructions get relayed back through the class. If you didn't hear it, ask. If you heard it, repeat it. Silence in formation gets the class smoked.
Recovery Blocks
Three deload weeks are built into this plan: weeks 4, 8, and the full taper in weeks 11 and 12. These are not optional. They are the weeks where adaptation actually happens. Skipping them is the most common way to show up to event day already injured.
Weekly recovery rules. Sunday is always off or light walking only. No ruck. No PT. Eat a high-protein recovery meal within an hour of your Saturday long ruck. Sleep 8 hours minimum during volume blocks (weeks 5 through 7 and weeks 9 and 10). If you're sleeping 6, you're training to fail.
Injury triage. Knee, hip, or lower-back pain that persists more than 48 hours is a stop sign. Drop volume by 50% the following week and see if it clears. Pain in the same spot for two weeks running gets a physical therapy visit, not another long ruck. Heavy DNFs caused by old injuries flaring mid-event are entirely preventable.
The final 7 days. Week 12 is short, easy, and boring on purpose. One 6-mile ruck on Tuesday. Some light PT Wednesday. Walking on Friday. The event starts Friday or Saturday evening. Your job in event week is to show up rested, hydrated, and a few pounds heavier than your usual training weight. The time to be fit was 11 weeks ago. The time to be fresh is now.
That's the plan. Earn the Tough first. Build to the prerequisites. Run the 12 weeks. Show up rested. The Heavy is the event everyone talks about for the rest of their lives. The people who finish do so because they trained for a year, not because they got lucky for 24 hours.

Frequently Asked Questions
- Should the GORUCK Heavy be my first GORUCK event?
- No. GORUCK is explicit about this on every Heavy event page: this should not be your first event. The Heavy is the pinnacle of the Challenge series and assumes you have already finished a Tough at minimum, ideally a few Toughs. The team-weight dynamic, the Cadre standards, and the sleep deprivation are not things you want to learn for the first time at hour eighteen.
- What are the PT standards for the GORUCK Heavy Welcome Party?
- The Welcome Party uses Army Physical Fitness Test standards. 2 minutes of push-ups, 2 minutes of sit-ups, and a 12-mile road march in under 3 hours and 30 minutes. You need to hit at least the 60% mark for your age and gender bracket to pass push-ups and sit-ups. Most participants who train aim to clear 70 to 80% to give themselves margin when fatigue hits.
- How much weight do you carry in the GORUCK Heavy?
- If you weigh 150 pounds or more, your ruck must weigh 35 pounds dry (no water, no food). If you weigh under 150 pounds, the requirement is 25 pounds dry. The class also carries one 25 to 50 pound team weight (typically a sandbag, sometimes more) plus an American flag. Cadre weigh your ruck at the start. They'll also spot-check throughout the event.
- Will the Cadre take my food during the GORUCK Heavy?
- Sometimes, yes. GORUCK Cadre are known to confiscate food at the start or during the event, especially energy gels and bars they consider "performance enhancing." Train hungry occasionally. Don't let your fueling strategy depend on a specific bar you packed. Real food eaten on a normal schedule before the event matters more than what's in your pack.
- How long is a GORUCK Heavy in hours and miles?
- Officially 24+ hours and a minimum of 35 miles of movement. Most Heavy events run 24 to 30 hours and cover 35 to 50 miles depending on Cadre and location. The 12-mile timed road march is part of the total distance. Don't train to the minimum. Train to the upper end so the event feels manageable instead of impossible.
- Do you sleep during the GORUCK Heavy?
- No. The Heavy is a continuous event with no scheduled rest. You eat on the move, you change socks during brief halts, and you stay on your feet for the full duration. Sleep deprivation is part of the training. Practice it in the final 4 weeks by doing one overnight ruck where you start at 8 p.m. and finish at sunrise.
- What is the difference between GORUCK Tough and GORUCK Heavy?
- Tough runs roughly 10 to 12 hours, 15 to 20 miles, with similar weight. Heavy runs 24+ hours, 35+ miles, with the added Welcome Party PT test, a longer 12-mile timed ruck, and significantly more team weight handling. The mental gap is bigger than the physical gap. Heavy is where Cadre stop coaching and start testing.
