      3. WEIGHT / AGE DIVISION
        • Men and Women may race together or in sperate gender categories.

          Category Division Weight
          A Light Weight < 75 kg
          B Medium Weight 75 – 84.9 kg

          2. After the weighting procedure, in case the total number cannot be divided by four, the first category with one competitor more will be determined upon a random draw. In case two competitors have the same weight, the younger competitor will be considered the lighter.
          3. Before the start of the first race, a second weighting procedure can be called for the athletes close to the limits of the categories, in order to recheck the correct registered weight.
        3. Weighing Procedure
          1. Weighing of competitors will be conducted during the event registration period on the official scales provided by the Race Committee.
          2. Competitors will weigh in T-shirt and shorts only (no footwear) – with all pockets emptied.
          3. Competitors may be re-weighed at any time during an event at the discretion of the Race Committee.
          4. If subsequent weighing of a competitor indicates a variation of more than 2 kilograms from the original weight that would cause a competitor to change weight division the Race Committee will assess the circumstances and have the option to change the competitors’ division.
        4. In National and International events competitors will be allocated to Age divisions as follows:
          Age Division Age
          Junior Under 15 years on the 1st racing day of the Event
