From November 2025 onward, indoor track and field will look, feel, and be judged very differently. World Athletics has introduced a set of competition rule changes that quietly but decisively reshape how races are run, how relays are managed, and how fairness is enforced on short indoor tracks.
While the changes may look technical on paper, they directly affect race tactics, medal outcomes, and athlete safety — especially in events like the 400m, 800m and indoor relays where lane geometry and congestion have long created distortions.
These reforms mark the most significant rethink of indoor track mechanics in decades.

Unlike outdoor tracks, indoor ovals are only 200 metres long. The curves are extremely tight, meaning athletes in inside lanes are forced to run sharper turns at higher centrifugal force. This increases injury risk and makes lane 1 and 2 objectively slower for long sprint events. Yet for years, indoor 400m and 800m heats used all lanes, forcing some runners into structural disadvantage regardless of ability. Add congested break-lines and chaotic relay exchanges, and indoor racing became less about speed and more about survival.
World Athletics’ new framework attempts to correct that imbalance.
1) The Indoor 400m is now a four-lane race: The most dramatic change is to the indoor 400m. From now on, heats at the World Indoor Championships will feature only four athletes per race, running exclusively in lanes 3 to 6. Lanes 1 and 2 will remain empty.
This is not cosmetic it removes the two worst lanes on the track.
Lane 1 in particular forces runners to take such a tight radius that they lose stride length and speed, while lane 2 still carries a measurable disadvantage. By restricting races to the middle lanes, World Athletics has effectively normalised race geometry.
This will: Reduce injury risk, Improve tactical racing and make times more comparable by removing the “bad-lane lottery”
Indoor 400m medals will now be decided by who runs fastest not who draws best.
2) The 800m break-line moves to 165 metres: Previously, indoor 800m runners were allowed to break into lane 1 after only about 65 metres. That meant eight athletes were funneling into a single narrow lane after just one curve a recipe for clipping heels, elbows, and falls. Now, the break-line is pushed back to 165 metres, the same point used in the 400m. Runners stay in their lanes for nearly a full lap before merging.
This creates more separation before contact along with fewer pile-ups and less first-bend bullying getting a cleaner tactical race. The result is closer to outdoor 800m dynamics, where positioning is earned rather than forced. For developing athletes and those without aggressive blocking skills, this is a massive step toward safety and fairness.
3) Dropped batons no longer require returning to the exact spot: One of the most controversial and confusing relay rules has finally been fixed. Earlier, if a baton was dropped, the runner had to return to the exact point where it fell — a judgement almost impossible to make accurately without slow-motion replay. Teams were often disqualified for marginal positioning errors rather than competitive advantage.
Now the athlete who dropped the baton must retrieve it, they may leave their lane to get it and must not shorten the race distance. They must not impede another athlete and must finish with the baton in hand and don’t need to return to the precise drop location.
This is a far more rational approach. Dropping the baton is already a major disadvantage. The new rule prevents teams from being eliminated for technicalities that have nothing to do with sporting fairness.

However, one key restriction remains: If an athlete picks up the baton and runs inside another team’s lane, the team is still disqualified. That preserves lane integrity while removing needless bureaucracy.
4) Relay takeovers now follow race order, not lane draw: Indoor 4×400m and 4×800m relays used to descend into chaos at the final changeover. Multiple runners would enter the takeover zone simultaneously from different lanes, creating collisions, blockages, and accidental interference.
Under the new rule, outgoing runners line up in the takeover zone based on the actual running order of their teammates, not their original lane draw.
So if your first runner is leading, your second runner lines up closest to the inside. If you’re fourth, you line up fourth.
This applies to:
- 4×400m
- 4×400m mixed
- 4×800m
This system mirrors outdoor relay zones and ensures that the team in front is not cut off by someone who was slower but happened to draw an inside lane.
It turns chaos into logic. What this means for athletes
Indoor racing is no longer a gamble of geometry. It is now a test of speed, positioning, and execution — the way it should be.
For 400m and 800m runners, this means there are fewer unfair eliminations, Safer racing & more honest results
For relay teams, it means:
- Fewer arbitrary disqualifications
- Clearer officiating
- Cleaner competition
And for spectators, it means races that make sense.

India’s indoor presence is growing especially in 400m, 800m and relays. These rule changes remove many of the structural disadvantages Indian runners faced on tight European tracks where lane draws and congestion often decided outcomes. Now, preparation, fitness, and race intelligence will matter more than luck.
That is exactly what a rising athletics nation needs.
World Athletics has not merely tweaked the rule book. It has rebuilt the architecture of indoor racing. And for once, fairness has finally caught up with speed.
