A triathlon is an endurance multisport that consists of swimming, cycling and running over various distances.

The objective of this sport is to see which athlete has the fastest overall time combined with each of the sports.

Each athlete competes for themselves.

• A bicycle
• Elastic laces to reduce any unwanted time for tying shoe laces.
• Helmet for cycling to protect against any falls.
• Running shoes
• Race belt to safely keep the athletes race number.
• Swim cap to keep swimmer’s hairs from getting wet.
• Goggles so that swimmers can see where they are going.
• A tri-suit, which is worn throughout all three portions of the race. This saves athletes time from changing.
• A wetsuit for swimmers if the water temperature is extremely cold.
