The weight throw is the event most officials meet for the first time indoors. It looks like a short hammer throw, it uses the shot put circle, and it needs a cage — which makes it the event most likely to be scheduled badly, officiated inconsistently, or run without the safety setup it requires.
This guide covers running one safely and correctly, from equipment check to tiebreakers.
What the Weight Throw Is
An athlete throws a metal weight attached by a chain or wire to a handle, from a throwing circle, into a marked sector. Technique resembles the hammer throw but compressed: because the implement is heavier and shorter, throwers typically use one to three turns rather than the hammer's three or four.
It is contested almost exclusively indoors, during the indoor season, and it does not appear on the outdoor programme. World Athletics does not recognise it, so the governing rules come from your national federation, state association, or the NCAA.
Implements: Confirm Before You Assume
This is the detail most likely to be wrong at your meet. Implement weights differ between the NCAA, the NFHS, and individual state associations, and some states contest weights that others do not.
The commonly cited figures are a 35 lb implement for collegiate men and 20 lb for collegiate women, with lighter implements at high school level — but high school weights in particular vary, and secondary sources disagree with each other.
Check the current rulebook for your level and your state, every season. Do not carry a figure over from another state's meet, from a catalogue, or from a previous year. An incorrect implement invalidates every mark thrown with it.
What to verify for each implement:
- Total weight, including head, chain or wire, and handle
- Maximum overall length
- Condition — no cracks in the head, no kinks or broken strands in the wire, no deformation of the handle
- That it is on your association's approved list, where one exists
Inspect and impound personal implements the same way you would for shot put or discus. Mark approved implements clearly, and make every approved implement available to every competitor.
The Circle, Cage, and Sector
The circle. The weight throw uses the same circle as the shot put and hammer — 2.135m (7 feet) in diameter. Unlike the shot put, there is no toe board; the circle rim is the boundary.
The cage. A cage is required. The weight leaves the circle at speed on a tangent, and an implement released early travels in a direction nobody expects. Check that the netting has no holes, that panels are secured, and that the gate configuration matches the direction of throw. Never run the event without a cage because a cage is inconvenient to move.
The sector. The landing sector is 34.92° — the same sector used for hammer and discus. A practical way to check it is laid out correctly: the two sector lines should be 12m apart (±0.05m) at a point 20m from the centre of the circle.
Mark the sector lines clearly. Indoors, where the throwing area often doubles as warm-up space, the sector edges need to be obvious to people who are not watching the event.
Pre-Meet Equipment Check
Work through this before the first athlete enters the circle:
- Cage — netting intact, panels secured, gates set for the throwing direction
- Circle — rim flush and unbroken, surface clean and dry, no wear at the back where throwers pivot
- Sector — lines visible for their full length, angle verified
- Implements — weighed, measured, inspected, impounded
- Measuring equipment — tape or EDM, plus marking pins or discs
- Landing area — clear of equipment, bags, and people; crossing routes marshalled
- Officials — know the signals for valid, foul, and pass, and know who clears the sector
Indoors, add one more: confirm the facility permits the event on that surface, and whether an indoor-only implement is required to protect it.
Running the Competition
Flights and order
With a large field, split into flights. Seed by entry mark so that stronger throwers compete later, which keeps the competition interesting and gives officials a rhythm before the biggest throws.
Attempts
The standard format is three preliminary attempts for every competitor, then the leading group — commonly the top eight or nine — advancing to three further attempts. Competition order for the finals is usually reversed, so the leader throws last.
Confirm the number of attempts and the size of the final group against your association's rules; both vary.
Time per attempt
An athlete has a fixed time to begin the throw once called, typically one minute. Start timing when the athlete's name is called and the circle is clear. Be consistent: time every athlete the same way, and announce when time is running short.
Between attempts
The implement must be carried back, never thrown or rolled back. Nobody enters the sector until the official signals it is clear. The thrower leaves from the back half of the circle, after the implement has landed.
Legal Throws and Common Fouls
A throw is a foul if the athlete:
- Touches the top of the circle rim or the ground outside the circle during the throw
- Leaves the circle before the implement lands
- Leaves from the front half of the circle
- Lets the implement land outside the sector lines
- Fails to begin the attempt within the allotted time
- Releases the implement and it strikes the cage and rebounds — conditionally; rules differ on whether a throw that hits the cage and still lands legally in the sector counts, so check your rulebook
A throw that touches the cage and lands in the sector is the most common point of disagreement between officials. Settle the interpretation at the pre-meet briefing, not mid-flight.
Dropping the implement without an attempt is generally not charged as a foul if the athlete has not begun the throwing motion — but once the motion starts, it is an attempt.
Measuring a Throw
- Mark the nearest edge of the mark made by the head of the implement — not the handle, and not the centre of the crater.
- Measure from that mark to the inside edge of the circle, along a line through the centre of the circle.
- Record to the lower whole unit, per your association's convention — fractions are not rounded up.
- Clear the sector before the next athlete is called.
Only the head's landing position matters. If the implement lands head-first and the handle whips outside the sector, the throw is still measured from the head's mark, and remains legal if the head landed inside the sector.
Safety
The weight throw has the least forgiving geometry of any throwing event indoors, in the most crowded building of the season.
- The cage is not optional. No cage, no event.
- Clear the sector between every attempt, and assign one official whose only job is that.
- Mark crossing routes. Athletes heading to warm-up should never cross a live sector.
- Watch the back of the circle. Worn or damp surfaces behind the circle cause slips during the turn, which is where early releases come from.
- Stop for anything. A spectator wandering into the sector is a reason to halt the flight, not a reason to hurry the next throw.
Tiebreakers
Ties on the best mark are broken by comparing each athlete's second-best mark. If those are also equal, compare third-best, and so on. If every mark is identical, the tie stands — for places that determine advancement or awards, check your association's procedure, as some require a throw-off and others do not.
This is why every attempt must be recorded, not just each athlete's best. A tiebreak cannot be resolved from a card that only shows the leading mark.
Using Meet Software for the Weight Throw
The weight throw produces exactly the record-keeping problem that paper handles badly: every athlete, every attempt, and a tiebreak that depends on the full history.
- Record each attempt as it happens, including fouls and passes
- Rank automatically by best mark, with second-best tiebreaks applied without anyone rebuilding the card
- Cut to finals and reverse the order without recalculating by hand
- Publish results as the flight finishes, instead of after
RecordBoard supports the weight throw as a standard indoor event, records every attempt from the judge's phone at the circle, and applies the second-best tiebreak automatically.
