FORGED IN FAILURE. FUELED BY GRIT.
If there’s one thing I’ve learned from grinding out 3+ hour rucks with 35 pounds on my back and 3,000 feet of elevation—it’s this:
Fueling isn’t optional. It’s essential.
The way I eat before, during, and after those efforts doesn’t just affect my performance—it determines whether I finish strong or fall apart.
This isn’t theory. It’s the strategy I’ve built through trial, error, and a lot of miles. With guidance from Omni Athlete Training Systems, I’ve finally dialed in a nutritional path that works—one that supports my goals in the mountains and beyond.
Whether you’re training solo or gearing up for your next endurance event, here’s how I fuel the long haul.
🥣 Pre-Ruck Nutrition: What I Eat Before a Long Ruck
Fueling starts before the first step. I treat my pre-ruck meal like it sets the tone for the entire effort.
Here’s what I eat before a long training ruck or event:
- 3 egg whites + 1 whole egg
- 1 cup of oatmeal with honey
- A handful of blueberries
Simple. Reliable. It gives me a clean mix of protein and slow-burning carbs without weighing me down. I’ve used this combo enough times to trust it in any environment.
Hydration starts early, too. I drink water and sip electrolytes before I even lace up. Start fueled. Start light.
🥾 Fueling During a Long Ruck (3+ Hours)
Most of my training rucks are no joke—35# dry, 3+ hours, and 3,000 feet of elevation on mixed terrain. Fueling during these is non-negotiable. Here’s my system:
🔹 Real Food First
I start every ruck with real food, as long as my gut can tolerate it:
- Clif Bar Minis
- Oatmeal cookies with chocolate chips
- Trail mix — salty, sweet, and easy to eat on the move
🔹 Transition to Quick Fuel
As the effort ramps up, I move to fast-acting fuel:
- Honey Stinger waffles and chews
- GU and HUMA gels
- Clif Bloks
- Skratch chews
I rotate flavors constantly to avoid palate fatigue. It’s one of the biggest mistakes people make—getting sick of what they’re carrying.
🔹 My Liquid Fuel Game-Changer
- 100g carbs
- 1000mg sodium per serving
- I use multiple servings over long rucks
It forms the backbone of my fueling plan—accounting for about half of my total carb intake. The rest comes from food and quick-digest options.
My personal target:
- 60–80g of carbs per hour (about 240–320 calories)
- 24 oz of water per hour
Even with Hyperlyte, I always carry fresh water. It keeps digestion smooth, energy steady, and it’s essential in the heat.
🔹 When Heat Hits: Electrolyte Shot
If cramps start creeping in, I reach for Protekt electrolyte packets and take them like a shot. Fast, efficient, and they’ve saved more than one climb.
⏱ What I Aim For During Long Rucks:
- 60–80g of carbs per hour
- 24 oz of water per hour
- Start fueling early. Don’t wait until you crash.
🧃 Post-Ruck Recovery Nutrition: Rebuild the Right Way
Once I stop moving, recovery starts immediately. I don’t wait to get home—I start refueling within 30–60 minutes.
- Skratch Labs Recovery Drink – great carb:protein ratio
- Clean water + more electrolytes
- Solid meals to back it all up
Post-Ruck Meals:
- Lunch – Grilled chicken, brown rice, and vegetables
- Dinner – A steak, broccoli, and a baked potato with butter, sour cream, and cheese
Recovery isn’t a reward—it’s part of the training. Eat like it matters—because it does.
💡 What I’ve Learned About Fueling for Endurance Rucks
I’ve bonked before. Hard. I’ve fought cramps, fatigue, and the quiet voice in my head telling me to stop. Every failure taught me to be more prepared next time.
Now I know:
- Fuel early. Fuel often.
- Start with real food. Transition smart.
- Switch up flavors. Avoid palate fatigue.
- Hydrate smart—Hyperlyte, Protekt, and water.
- Train your gut before the event.
- Recover like performance depends on it—because it does.
And here’s something I’ve learned the hard way: Nutrition evolves as you train.
What your body can handle in Month 1 isn’t what it can handle in Month 6. Building up your carb intake is just like building strength—it takes time, reps, and consistency. You have to train your fueling strategy like you train your endurance.
Even now, my own nutrition continues to evolve. What works today might shift next season as training loads, recovery needs, and goals change. I’m still refining—because that’s part of the process too.
⛰ Final Thoughts: Fueling Is a Skill, Not an Afterthought
Rucking in the mountains will strip you down. That’s the point. But if you want to stay sharp, move strong, and finish what you start—you need to fuel like it matters.
Thanks to Omni Athlete Training Systems, I’ve built a sustainable strategy that works for me in the mountains, on the trails, and during training blocks that would’ve broken me years ago.
It’s not about being perfect. It’s about being prepared—and adapting along the way.
