Running with a Ruck: Mastering Shorter Strides for Maximum Performance
Introduction: Why Ruck Running is Different
So, you’ve strapped on a weighted ruck, ready to crush your fitness goals. But halfway through, your back aches, your shoulders scream, and your ruck bounces like a hyperactive jack-in-the-box. The problem? Your gait.
Running with a ruck is NOT the same as traditional running. Missteps lead to excessive bouncing, wasted energy, and potential injuries. Research by Birrell et al. (2007) highlights that running amplifies load movement, increasing strain and reducing efficiency. The key? Adjusting your gait for optimal performance.
The Secret Weapon: Shorter Strides for Maximum Efficiency
A shorter stride stabilises your load, minimises bounce, and protects your joints. Walsh et al. (2021) confirm that "vertical oscillation of the load is a primary factor in energy loss and discomfort during rucking." In simpler terms, less bounce equals greater efficiency.
Why Shorter Strides Work:
- Better Stability: More ground contact time means better balance under load.
- Energy Efficiency: Less upward motion = less wasted energy.
- Joint Protection: Shorter strides reduce impact on ankles, knees, and hips.
The 4-Strike Gait: Your New Best Friend
Most runners use a 3-strike gait (heel-to-toe or midfoot strike). For rucking, switching to a 4-strike gait improves stability and load distribution.
How to Ruck Like a Tank, Not a Trampoline:
- Land with a flatter foot to spread impact forces.
- Keep steps short and controlled (no overstriding!).
- Engage your core to maintain posture and balance.
Common Mistakes (And How to Fix Them)
- Running with a Heavy Load: Sprinting with a ruck increases joint strain—stick to a controlled, brisk pace.
- Ignoring Strap Adjustments: Loose straps cause ruck instability—tighten them up so the load sits close to your body.
- Neglecting Form: Shoulders back, core tight, smooth steps forward. Treat rucking as a deliberate, powerful movement.
Ruck Training Plan: Progressing the Right Way
| Week | Activity | Ruck Weight |
|---|---|---|
| 1-2 | 3x per week brisk walking | 10% body weight |
| 3-4 | 4x per week, add jogging intervals | 10-15% body weight |
| 5-6 | Continuous jogging for 15 min | 15-20% body weight |
| 7-8 | Increase weight, maintain steady pace | 20% body weight |
The Takeaway: Ruck Smarter, Not Harder
By adjusting your stride, adopting a 4-strike gait, and treating rucking as a controlled movement, you’ll maximise efficiency while minimising discomfort. Walsh et al. (2021) emphasise that "adjustments in gait mechanics, including stride length, play a critical role in optimising load carriage efficiency."
So, next time you gear up, remember: short strides, strong posture, and smooth transitions.
