Running and fixed rigs: where the resistance is
Explainer · Last reviewed 2026-08-14
The most consequential structural choice in terminal tackle. Whether a fish meets the weight when it moves the bait decides how the bite registers, how the hook is set, and what the fish does next.
A RUNNING RIG lets the line slide through or past the weight. A fish picking up the bait draws line through the weight and feels only the friction of line moving through a ring. The weight stays put.
A FIXED RIG has the weight locked into the load path. A fish moving the bait moves the weight, or bolts against it.
EVERYTHING ELSE FOLLOWS FROM THAT.
HOW THE BITE LOOKS. On a running rig, the bite is line moving — the tip pulls round steadily, or line peels off a slackened spool. It requires the angler to do something. On a fixed rig, the fish frequently hooks itself and the bite is violent and unmissable, which is precisely why the arrangement was invented.
WHO HOOKS THE FISH. A running rig needs a strike, and needs it at the right moment. A fixed rig sets its own hook against the weight, which is a real advantage when the rod is in a rest at distance, and a real disadvantage when the fish is small enough that the weight simply drags.
WHAT A CAUTIOUS FISH DOES. This is where the running rig earns its keep. A fish that feels resistance early frequently drops the bait, and in clear, pressured or low-flow water that is the difference between bites and none. Where the fish is confident and the ground is clean, the self-hooking arrangement wins.
AND THE WELFARE CONSEQUENCE, WHICH IS THE ONE MOST OFTEN LEFT OUT. A fixed rig hooks the fish quickly and usually in the mouth, which is good. A running rig fished with the bait left too long lets a fish swallow it, which is not. Neither family is inherently kinder — the outcome depends on how promptly the bite is answered, and that is under the angler's control on a running rig and largely out of it on a fixed one.
THE SAFETY REQUIREMENT ON FIXED RIGS IS ABSOLUTE. If a fish is attached to a fixed weight and the line parts above it, the fish is towing that weight indefinitely. Every fixed arrangement must be built so the weight can separate — a lead that pulls off its clip, a link that is deliberately the weakest component. This is not an optional refinement, and it is the single most important thing about the family.
SEMI-FIXED IS THE COMMON COMPROMISE: a weight held firmly enough to bolt the fish and released by a sharp pull or by the fish's own weight if the rig is broken. It is the standard modern answer and it is only as good as the release mechanism, which should be tested by hand every session rather than assumed.
The other things pulling, which are not fish
The argument above is about what a fish feels. In practice a rig spends most of its time being pulled by things that are not fish, and both arrangements handle that badly in opposite ways.
TIDE AND CURRENT PULL CONTINUOUSLY. On a running arrangement, flow drags line through the weight, which means the bow between rod and rig grows steadily and a bite arrives at the rod tip late, weakly, or not at all. On a fixed arrangement the whole rig moves instead, until it finds something to hold against.
WIND DOES THE SAME THING THROUGH THE ROD. A bow of line between rod tip and water catches wind and pulls just as a current does, which is why a rod pointed into the wind and held low fishes a running rig far better than one held high.
WEED AND DEBRIS COLLECT AND PULL. On a running rig, weed on the line adds drag at the weight and eventually locks it, converting the arrangement into a fixed one without anybody deciding to. That is worth knowing because it happens silently: an angler thinks they are fishing a sensitive running rig and is in fact fishing a jammed one.
AND THE ANGLER PULLS, WHICH IS THE ONE PEOPLE FORGET. Tightening down to a fixed lead sets the hook; tightening down to a running lead pulls the bait towards the weight and can move it out of the spot it was cast to.
WHICH IS WHY THE CHOICE IS FREQUENTLY MADE BY CONDITIONS RATHER THAN BY FISH. Still water with a shy fish is a running rig's case. Strong tide at range with the rod in a rest is a fixed rig's case, because a bite will never reach the rod otherwise. Weed argues for fixed, because a running arrangement will jam anyway and it is better to have chosen it.
AND THE SAFETY CONSTRAINT SITS ABOVE ALL OF IT. Whatever the conditions argue for, the arrangement has to be one a fish can shed if the line parts. That is not a trade-off against the rest; it is a precondition.

Where to go next
Gear this affects
- Hair rigThe hair rig's hooking mechanism depends on the fish moving off against resistance, which is why it is fished semi-fixed and why the two ideas developed together.
- Method feeder rigA short hooklength against the weight of a loaded feeder is the fixed family in its most concentrated form: the fish hooks itself and the angler's timing plays almost no part.
- Running legerThe canonical running arrangement, and the clearest demonstration that a bite on this family is line moving rather than a rod wrenching round.
- Uptide rigAn instructive edge case for the running/fixed distinction: the lead is fixed while it grips and effectively free once it breaks out, so the arrangement changes category during the take.
