Walking with weight
A loaded ruck is still walking, but the pack changes your posture, your steps and your feet. These points come from the US Army's foot march manual.
Lean from the ankles, not the back
With a pack you lean forward a little, even with loads as light as 15 to 20 pounds. That lean keeps the load over your feet and is normal. Leaning too far forward strains the lower back and the stomach muscles: stand tall, and let the lean come from the ankles rather than from a bent back.
Shorter, quicker steps spare your feet
Under load, a shorter, quicker step is described as desirable because it can reduce stress on the bones of the foot; a longer stride under a heavy backpack may do harm.
A steady pace beats a fast one
Keep a moderate, steady pace: the manual warns that moving too fast, even in good conditions, brings early fatigue and more rest stops. Hills and steep grades slow every march; take them carefully, uphill and down.
If your plan's goal pace is faster than most people walk, the plan says so: you will jog with the pack for part of the ruck. Learn that at the plan's lighter loads, never at full load first.
Halt early, then briefly every hour or so
The manual suggests an adjustment halt in the first half hour to fix laces, straps and layers, then short rests every hour to hour and a half. Keep them short so your muscles do not stiffen.
| Halt | When | What for |
|---|---|---|
| Adjustment halt | First half hour | Laces, straps, layers |
| Short rest | Every 1 to 1.5 h | Rest, kept short |
Treat a hot spot before it becomes a blister
- Socks: wool cushion-sole socks offer good protection; synthetic socks, or a thin synthetic sock inside a thicker one, reduce blisters.
- Boots: fit new boots carefully, and tape known hot spots before you wear a new pair.
- On the march: blisters are one of the most common march problems. At a halt, take off one boot at a time, change socks and treat a hot spot before it becomes a blister.
