Medley relay order vs individual medley order

Notice freestyle is last in both, and breaststroke and butterfly swap places in the middle. The easiest memory trick: the relay order is the IM order with the first two strokes swapped.

In the individual medley, butterfly goes first because it is widely considered the most physically demanding stroke, so swimmers tackle it while they are freshest. In a relay, that logic doesn't apply in the same way, because each swimmer is only racing their own single leg, not managing fatigue across all four strokes.

Instead, the medley relay starts with backstroke for a practical reason: a backstroke start happens in the water, with the swimmer holding the wall, rather than diving in from the block. That makes it a natural first leg. From there the order runs breaststroke, then butterfly, then freestyle fastest-finishing leg last.

It helps to think of the medley relay order as building up in difficulty for the takeover itself, not for the swimmer. A backstroke swimmer leaving the water hands over to a breaststroke swimmer diving in from the block, then on to butterfly, then freestyle anchors the race home. Coaches usually pick the relay order based on who swims each stroke best individually, then slot that swimmer into the matching leg of the fixed sequence, rather than choosing the order itself, which the rules already fix.

The most common mistake isn't the order itself, it's a team lining up for an individual medley event using the relay order, or vice versa, out of habit. Younger swimmers in particular will often default to whichever order they learned first and swim it automatically under race pressure. A quick call-out from the coach or team captain, confirming backstroke first for the relay and butterfly first for the IM, right before marshalling, catches this before it becomes a disqualification.

If your meet runs a mixed medley relay, check the program notes for that specific event, since the stroke order itself (backstroke, breaststroke, butterfly, freestyle) stays the same, but the exact conditions for that event are set out in that meet's own program rather than the general medley relay rule.
