Carrying Quickle by Kit and Sport
The Carry page covers the principle: a stick goes wherever your kit has room. This page is the specifics, because the best spot genuinely differs by what you're running, riding, or hiking with, and a few details save you from fumbling at the worst moment. None of this is complicated. It's just worth knowing before you're standing on a trail with a locked calf, digging through a pack.
Running vest or belt
Keep a stick in a front pocket, the same place you'd stash a gel you want fast. The point of a vest is reachability without stopping, and a cramp is exactly when you don't want to wrestle your pack off. If you run with soft flasks, carry the stick dry and mix it into a flask at the moment rather than pre-mixing, brine sitting in a flask all day is worse to drink and ties up a flask you want for water.
On the bike
A jersey pocket is the natural home, or a small top-tube or stem bag if you run one. What we'd steer you away from is burying it deep in a frame bag under everything else, or anywhere it rattles loose over rough roads. On a hot ride the powder is happiest not baking against a dark frame in the sun all day. Reachable and shaded beats tucked and forgotten.
Backpacking or thru-hiking pack
Hip-belt pocket or pack lid. Both keep a stick grabbable without dropping the pack and opening the main compartment, which matters when a cramp hits at the end of a long carry. For multi-day trips, a couple of sticks per resupply box weigh nothing and mean you're never relying on a trail-town store. The dry format is the whole reason it earns space in a kit where you've counted every gram.
Wherever it lives, keep it somewhere you can reach without taking your kit off. A cramp tool buried under your gear is a cramp tool you'll skip when your leg locks and you just want to keep moving. Reachable beats tidy every time.
A single stick of Quickle carries 700mg sodium, 300mg potassium, and 50mg magnesium, plus the real vinegar that does the fast work, in a package small enough to fit any of these spots without a second thought. Pick the one that matches your kit, and then forget about it until the day you need it.
Quick answers.
Where should I keep it in a running vest?
A front pocket, within reach without stopping, like you'd keep a gel you want fast. A cramp is exactly when you don't want to take your vest off to dig for it. If you use soft flasks, carry the stick dry and mix at the moment rather than pre-mixing.
Should I pre-mix it in a flask or bottle?
Better to carry it dry and mix at the moment. Pre-mixed brine sitting all day is less pleasant to drink and ties up a flask you'd rather keep for water. The dry stick is the format's advantage, so use it, mix only when a cramp shows up.
Where does it go on a bike?
A jersey pocket or a small top-tube or stem bag, somewhere reachable and shaded. Avoid burying it deep in a frame bag or letting it rattle loose, and avoid letting it bake against a dark frame in the sun all day. Reachable beats tucked away.
Best spot in a backpacking pack?
A hip-belt pocket or the pack lid, so you can grab it without dropping the pack and opening the main compartment. For multi-day trips, stash a couple of sticks per resupply box; they weigh nothing and mean you're not relying on a trail-town store.
