Running Rig: How to Tie and Fish It

The running rig lets the lead run freely on the mainline above the hooklink, so a taking fish feels the rod tip rather than a fixed lead. On pressured waters where carp have learned to deal with semi fixed setups, and for shy biting fish in general, it shows you bites you would otherwise never see.

1. 1

   Thread the run ring onto the mainline

   Slide a run ring or free running clip, with the lead attached, straight onto your mainline. The lead must be able to run genuinely freely, so avoid anything that grips the line.

2. 2

   Add the buffer bead

   Thread a rubber buffer bead on below the ring to protect the knot and stop the lead banging down onto the swivel on the cast.

3. 3

   Tie on the swivel

   Tie your mainline to a size 8 swivel with a grinner or palomar knot. The bead sits against this swivel, and the lead runs on the line above it.

4. 4

   Attach the hooklink

   Connect a 6 to 10 inch hair rigged hooklink to the swivel, either tied direct or loop to loop. A standard hair rig with a bottom bait or snowman is the natural partner.

5. 5

   Set up your indication

   Fish the rod tip low with the line reasonably direct to the rig. Because the line runs through the lead, movement at the rig translates into indication at the rod, which is the whole point of the setup; many anglers pair it with a sensitive bobbin.

6. 6

   Hit the indications

   Takes on a running rig are often steady pulls, lifts or drop backs rather than screaming runs, because there is little bolt effect from the lead. Watch closely and strike confident indications rather than waiting for the alarm to melt.

Running Rig: common questions

What is the difference between a running rig and a lead clip setup?

On a lead clip the lead is semi fixed, so the fish hits the weight of the lead and hooks itself: the bolt effect. On a running rig the lead runs free on the line, so the fish feels far less resistance and the bite registers at the rod instead. Running rigs give better indication; semi fixed setups give more self hooking.

Is a running rig safe for fish?

Yes, it is widely considered one of the safest lead arrangements in carp fishing, because the lead is never fixed to the rig. If the line breaks, the lead can slide away from the fish rather than tethering it, provided you use a genuinely free running ring and no leadcore behind it.

Do carp hook themselves on a running rig?

Less reliably than on a semi fixed lead, because there is little bolt effect. The hook usually takes hold as the fish moves off, and the angler converts the take by striking a positive indication. That is the trade off: more bites shown, slightly more angler input needed.

How heavy should the lead be on a running rig?

Around 2 to 3oz covers most situations. It needs enough weight to hold bottom and anchor the line so it can run through the ring properly on a take; too light and the whole lot moves with the fish, muffling the indication the rig exists to provide.
