A successful trail race takes preparation: for your body, your mind and your kit. A poorly organised pack can cost you time, bounce around or throw you off balance mid-race. Knowing how to pack your trail pack properly is essential.
The golden rules of weight distribution
Trail packs are designed to move with your body. To maintain a stable centre of gravity, place the heaviest items close to your back and in the middle of the pack. Also aim for an even balance between front and back. Soft flasks at the front, for example, help balance the weight of kit in the main compartment.
This arrangement stops the pack pulling you backwards or putting all the weight on your shoulders. It reduces muscle fatigue and helps you stay stable on descents.
As well as distributing weight properly, think about keeping everything secure. Packing efficiently and using compression straps help hold each item in place. This prevents uncomfortable bouncing during the race.
Organising your pack by accessibility
Good organisation helps you get the most from the best trail pack. The front and side pockets make up the immediate-access zone. Put everything you want to grab without stopping here, even on a climb or technical descent: hydration (soft flasks), nutrition (gels and bars) and small items (phone and whistle).
The top of your pack or the kangaroo pocket forms the quick-access zone. It lets you adapt easily to changing weather. Keep your windproof jacket or waterproof jacket, gloves, neck gaiter and spare food here.
Finally, the main compartment is the bottom zone of your pack. You rarely access it during a race because you have to stop to do so. Store mandatory safety equipment, your first-aid kit and a spare layer here.
Pro tips for packing your trail pack
To pack your trail pack properly, learn to remove excess air. This makes your pack more stable, reduces bouncing and helps it feel lighter. Roll clothes instead of folding them, use compression straps and fill gaps with small items. You can also squeeze your soft flasks and draw out a little air before closing them.
Moisture is a recurring problem in trail running. To stop your phone, documents or food from getting soaked, put them in freezer bags such as Ziploc bags. Spare clothes and bulkier items can go in waterproof bags such as dry bags.
There are several ways to carry your poles efficiently. Front shoulder-strap attachments give you quick access but can get in the way of your arms. Horizontal attachments at the back strike a good balance between stability and access, but require more flexibility. Finally, quivers on the back are stable, comfortable and well suited to long distances, although the poles are harder to reach.
What mistakes should you avoid?
There are a few mistakes to avoid when packing your trail pack. The first is keeping food in the main compartment, at the bottom of the pack. This means you have to stop to get to it, breaking your race rhythm.
Another mistake is overloading your pack with non-essential kit. In trail running, every gram counts, and unnecessary weight causes extra fatigue. Your stride may become less fluid, and your shoulders or back may start to ache.
Finally, failing to test how you’ve packed your bag before running your first trail race is a bad idea. On race day, you need to know that everything is in place and the weight is evenly distributed. Otherwise, you risk chafing, irritation or finding that you can’t reach some of your kit.
Packing your trail pack properly before a race is essential. Everything needs its place, and every movement should feel natural. That way, you can grab what you need without thinking about it and focus entirely on the race, not your pack.
