Discus Throwing Weight Rules
Discus requires both technical precision and compliant equipment.
According to World Athletics standards, senior men use a 2kg discus and senior women use a 1kg discus. Youth weights include 1.75kg (U20 men), 1.5kg (U18 boys), 1kg (U18 girls/U15 boys) and 0.75kg (U15 girls).
Throws are made from a 2.5m circle, and competition discus must meet strict specifications around rim weight distribution, diameter and construction. Using certified implements is essential for league and championship competition.
Athletics Direct stocks a wide selection of Polanik carbon and high-spin competition discus, Cantabrian competition models, and robust rubber training discus ideal for school environments.
For clubs and performance athletes, higher spin models can support improved flight stability and distance.
