Sandbag Sprint Relay | Friends

Quick Intro

In a Sandbag Sprint Relay two partners share one sandbag and one course. The first partner starts at the line with the bag on one shoulder and carries it as fast as they can to the halfway mark, where the second partner is waiting. They hand the bag over, and the second partner carries it on to the finish. The pair’s total time is the score, and the game is to beat it on the next run.

Carrying a sandbag on the shoulder, loading it up, keeping the torso upright and walking or jogging with it, is taught at Sandbag Shoulder Carry. This guide covers the relay: setting the course, the handoff, timing and splitting the legs.

What You’ll Need

One sandbag both partners can shoulder comfortably.
A flat, clear lane of 20 to 40 metres on grass, turf or a track.
Cones for the start, the halfway mark and the finish.
A timer. A phone stopwatch works: the second partner starts it on “go”, slips it into a pocket before the handoff, since the bear-hug exchange needs both arms, and stops it at the finish.

How to Play

Agree the course length, the bag weight and where the halfway mark sits.
The first partner stands at the start with the bag on one shoulder. The second partner stands at the halfway mark, facing back toward them.
Start the timer on “go”. The first partner carries the bag to the halfway mark.
At the mark, hand the bag over (see below).
The second partner carries it to the finish. Stop the timer when they cross the line with the bag still on the shoulder.
Set the bag down under control, walk back and reset.
Run three to five relays, resting fully between them, and try to beat the best time.

The Handoff

Most of the time a pair loses in this relay is lost at the handoff. A rushed exchange where the bag slides off a shoulder costs far more than a carry that is slightly slower.

A reliable way to pass the bag:

The carrier slows in the last few steps and arrives at the mark at a walk.
They bring the bag down off the shoulder to a bear hug against the chest.
The receiver takes hold of it with both arms while it is still held, so for a moment both partners have it.
The carrier lets go only once the receiver says “got it”.
The receiver lifts it to their own shoulder and sets off.

The bag goes hand to hand every time. It is never tossed, and it is never dropped at the mark for the other person to pick up. Practise the exchange slowly a few times before timing anything.

Timing and Rules

The clock runs from “go” to the finish, including the handoff.
The bag must be on a shoulder while moving. Carrying it in front at a run is a different exercise and does not count.
A dropped bag stops the run. Set it straight, and run again after a rest. The timed run does not continue from a dropped bag.

Making It Fair

The two partners score together, so the handicap is about sharing the work sensibly. The less conditioned partner carries the shorter leg, and the halfway mark moves to make that happen. For example, on a 30-metre course, one partner carries 12 metres and the other 18. Keep the same split for a session so times can be compared. For more on balancing work between partners, see Training With a Friend.

Staying Safe

A clear, flat lane. A trip with a heavy bag on one shoulder is hard to recover from.
Controlled handoffs only. The bag is passed from one person’s grip to the other’s, never thrown.
A bag both can carry. Pick a weight that the weaker partner can shoulder and move with at a quick jog without their posture breaking.
Swap shoulders between runs so one side is not carrying every time.

Common Mistakes

Sprinting into the handoff. Arriving fast means a sloppy exchange. Slow down for the last few steps.
Leaning away from the bag. The torso stays upright and braced. A big side lean slows you and strains the back.
Letting go too early. Wait for “got it”.
Racing every run all out. The second and third runs often go faster once the handoff is smooth.

Fitting It Into a Session

The relay is a short, hard conditioning effort. It fits after the main strength work or as the closing piece of a session, with several minutes of rest between runs. Three to five runs is plenty. For ideas on building the rest of the session around it, see Building a Partner Session.

Getting Better Over Time

Note the course, the bag weight, the split and the best time. Most pairs shave the most time off by tidying the handoff. After that, a longer course or a heavier bag keeps it hard.

Farmer’s Carry Relay runs the same relay with a weight in each hand.
Sled Push Relay splits a sled push into legs.
Two-Person Sandbag Carry has both partners carry one bag together.
Carry Steal includes a sandbag version, where one partner chases another who carries the bag.

FAQ

Can we race another pair?

Yes. Set two lanes side by side with the same course and bag weight, and the first pair to the finish wins.

How heavy should the bag be?

Light enough that both partners can jog with it on a shoulder for their leg. For most pairs that is a good deal lighter than their heaviest carry.

Which shoulder?

Either. Swap shoulders between runs so both sides get the work.
