How are jump and throw distances measured and recorded?

• Horizontal jumps and throws: distances are recorded to the nearest 0.01m below the distance measured if the distance is not a whole centimetre.
• When: the measurement of each jump or throw is made immediately after each valid trial (or after an immediate oral protest).
• Jumps: measured from the nearest break in the landing area made by any part of the body, or anything attached to the body at the time.
• Recording: except in the high jump and pole vault, a valid trial is indicated by the measurement taken.
• National championships: at Athletics Canada U16, U18, U20 and Open National Championships, an electronic device such as a laptop is mandatory for ranking athletes in the throws and horizontal jumps.
