Record 1 2020-11-18

English

Subject field(s)
  • Skiing and Snowboarding
CONT

Parallel slalom is all about carving, so hard boots and plate bindings are used with a rigid board which can cut through the snow and give a stable and faster ride. To cut down on air resistance, riders lean into the turns and wear skin-tight suits. Most wear knee-height shin guards as they often hit the gates as they pass them, and helmets protect the head.

CONT

Ivica Kostelic of Croatia and Maria Pietilae-Holmner of Sweden won the first parallel slaloms in the World Cup. The event in Munich was open to the top 16 Alpine skiers, who raced side by side down a 200-meter course that contained 20 gates.
