Why Is the Middle Lane Worth Winning? The Track Is Not Fair to Everybody
By the BrainSnail editorial team. How these articles are written and checked, and how to tell us when one is wrong.
Assigning lanes for a race sounds like a formality, and in several sports the lane a competitor gets measurably affects the result before anybody starts.
Why lanes are not equal
On an oval track, staggered starts equalise the distance run but not the geometry. An inside lane has a tighter bend, which forces a runner to lean further and lose speed through the turn. An outside lane has a gentler bend and no view of anybody ahead, since every competitor is behind the runner's shoulder for most of the race. Middle lanes combine a reasonably gentle curve with a view of several rivals, which is why competitors and coaches regard them as the ones to have.
Where the lane matters most
The size of the effect varies by event and by sport:
- •Two hundred metres, where the whole bend is run at full speed
- •Four hundred metres, for the same reason over a longer curve
- •Swimming, where outside lanes get more turbulence from the walls
- •Speed skating, where the inner lane is markedly slower
- •Rowing, where wind and current across a course differ by lane
- •Cycling sprints, where the inside position is a tactical disadvantage
How allocation is done
Most sports have moved from random draws to allocation by performance, on the reasoning that the advantage should go to the competitor who earned it. In athletics the fastest qualifiers are placed in the preferred central lanes and the slowest on the outside, using times from the previous round. Swimming does the same, putting the fastest qualifier in the centre lane with the next fastest either side, producing the wedge shape visible from the stands. Random draws survive where the lanes are genuinely comparable, and are still used in some rowing and canoeing events.
What happens where lanes are not used
Events run without lane allocation trade one kind of unfairness for another, which is worth noticing before assuming lanes are the problem. A mass start puts everybody on an equal surface and introduces position, contact and tactics, so a runner boxed in on the inside may be unable to move when they need to. Distance events are decided by that positioning as much as by speed. Cycling and skating in packs add drafting, which makes leading the race actively disadvantageous. Removing lanes therefore does not remove the geometry problem, it replaces a measurable disadvantage with a tactical one.
How large the effect actually is
Studies of the two hundred metres have found a measurable disadvantage for the innermost lanes, on the order of a tenth of a second or more compared with the middle, which is enormous in an event decided by hundredths. Swimming studies find smaller effects and disagree about whether modern pool design with deeper water and better lane ropes has removed them. The evidence is strong enough that world records set in outside lanes are sometimes discussed as more impressive. It is also strong enough that the allocation method is itself a subject of periodic complaint from competitors who narrowly miss a favoured lane.
The takeaway
Staggered starts equalise distance and not geometry, so inner lanes force a tighter turn and outer lanes remove any view of rivals, leaving the middle preferred. Most sports now allocate by qualifying performance rather than at random, producing the wedge of fast qualifiers in central lanes. In the two hundred metres the disadvantage of the innermost lanes is measurable and larger than the winning margin.
