[01]4x100 vs 4x400 Relay

Where the two relays diverge

Exchange technique: blind versus visual

The 4x100 exchange is blind and fast. The incoming runner calls the handoff, and the outgoing runner is already at full speed, arm back, never looking around. The 4x400 exchange is visual and slower by necessity, since the incoming runner is often badly fatigued after a full lap, so the outgoing runner watches the baton arrive and takes it as a controlled handoff rather than a blind stick pass. That single difference shapes almost everything else about how each relay is practiced.

Zone length and stagger

The 4x100 exchange zone is 30 meters total under the current rule, and every leg runs at least partly in a staggered lane since the whole race stays in lanes. The 4x400 exchange zone is 20 meters, and only the first two legs, plus part of the third depending on the meet, run staggered before the field breaks for the inside rail, which is where most of the race's passing and positioning actually happens. Misjudging the break is a common way teams lose ground they never quite get back.

Runner order and what wins each race

4x100 order favors a strong starter, the fastest legs in the middle where curve speed matters most, and a closer who finishes under pressure. Teams with four 11.3 sprinters who exchange cleanly beat teams with four 11.0 sprinters who fumble a zone. 4x400 order typically opens with the second-fastest 400 runner and saves the fastest for anchor, and depth decides it, since the slowest leg on a 4x400 team costs far more than the fastest leg gains back. There is no exchange-zone shortcut for a weak third leg in the 4x400.

Film your exchanges

Relay exchanges are the easiest part of track to film and the most rewarding. Side-on from 20 feet, capture the full zone. AI grades stick speed, hand position, and zone use. Most teams find 0.3-0.5 seconds in clean exchanges alone.

[10]Common questions

4x100 vs 4x400 Relay FAQ

Common questions athletes and coaches ask about this topic.

Which relay is harder, 4x100 or 4x400?
Different kinds of hard. The 4x100 is harder technically, since exchange precision at full speed leaves almost no room for error. The 4x400 is harder physically, since each leg is a full 400m run near race pace.
Why are 4x100 teams faster than the sum of their open 100m times?
Clean blind exchanges keep the stick moving at full speed across the entire zone, effectively adding a flying start to legs 2 through 4. Three good exchanges save more time than one slow individual leg loses.
Who should run lead-off in the 4x400?
Usually the team's second-fastest open 400m runner. Lead-off needs a good start and clean lane discipline through the staggered portion; the fastest closer is saved for anchor.
How long is the exchange zone in a 4x400?
20 meters, centered on the incoming runner's lane position, versus 30 meters in the 4x100 under the current rule.
