Why Are Relay Batons Hollow in Track & Field?
Summary
Relay races aren’t just about speed — the baton is central to the event. But have you ever wondered why it’s always a lightweight, hollow tube? The hollow design isn’t random — it’s chosen for weight, balance, safety, and performance. This guide breaks down the science and rules behind the baton.

The Basics of the Relay Baton
Shape: Cylinder, usually 30 cm long and 12–13 cm in circumference.
Weight: Hollow, often aluminum, ~50 g.
Rules: Must meet World Athletics standards (smooth, no sharp edges, not tapered).
Why Batons Are Hollow
| Reason | Explanation | Benefit |
|---|---|---|
| Weight | Hollow construction keeps it light (~50 g). | Less fatigue when sprinting 100–400m with it. |
| Grip & Control | Hollow tube allows even thickness all around. | Consistent handoffs, no wobble or imbalance. |
| Safety | No sharp ends or heavy materials. | Safer for athletes in case of contact. |
| Durability | Aluminum or polycarbonate resists bending. | Holds shape even after repeated drops. |
| Regulations | World Athletics specifies smooth, hollow design. | Uniform equipment across competitions. |
The Physics: Why Not Solid?
A solid baton would:
Be too heavy (slows acceleration and handoff reaction).
Risk slipping due to uneven weight distribution.
Pose a safety hazard if dropped or if athletes collide.
By being hollow, batons maximize speed, efficiency, and safety without sacrificing structure.
Relay Baton Rules (World Athletics)
Must be a hollow, smooth, circular tube.
Length: 28–30 cm.
Circumference: 12–13 cm.
Weight: At least 50 g.
No bells, whistles, or modifications allowed.
Any baton not meeting these specs risks disqualification.
FAQs
Q1: Can a team decorate their baton?
Yes, but tape, paint, or grips can’t change the shape or give an unfair advantage.
Q2: Why not use batons with grips or indents?
Because the rules require a smooth cylinder — no ergonomic shaping allowed.
Q3: Do youth meets use the same batons?
Yes, though plastic versions are common for cost and safety.
Q4: Can a baton break during a race?
Rarely — modern aluminum/polycarbonate batons are very durable.
Key Takeaways (TL;DR)
Batons are hollow for lightness, balance, safety, and durability.
A hollow baton = faster handoffs and safer racing.
World Athletics mandates specific dimensions and weight.
