#1
A triathlon is an endurance multisport event combining three continuous disciplines: swimming, cycling, and running in fixed sequence.
#2
The competition clock runs continuously from the starting horn of the swim until the athlete crosses the final running finish line.
#3
The race sequence is universally standardized as: first Swim, second Bike, and third Run.
#4
Transition 1 (T1) is the timed zone where athletes transition from the swim leg to the bicycle leg.
#5
Transition 2 (T2) is the timed zone where athletes rack bicycles and switch into running shoes for the final leg.
#6
Transitions are commonly referred to as the 'fourth discipline' of triathlon due to their direct impact on overall race placement.
#7
The first modern triathlon was organized on September 25, 1974, by the San Diego Track Club at Mission Bay, California.
#8
The Olympic Standard Distance triathlon consists of a 1.5 km (0.93 mi) swim, a 40 km (24.8 mi) bike, and a 10 km (6.2 mi) run.
#9
Triathlon made its official debut as a medal sport at the Sydney 2000 Summer Olympic Games in Australia.
#10
The Sprint Distance triathlon consists of exactly half the Olympic distance: 750 m swim, 20 km bike, and 5 km run.
#11
The legendary Ironman Triathlon, founded in Oahu, Hawaii, in 1978, comprises a 3.8 km swim, 180.2 km bike, and a full 42.2 km marathon run.
#12
The Ironman 70.3 (Half Ironman) spans a cumulative distance of 70.3 miles: 1.9 km swim, 90 km bike, and 21.1 km half-marathon run.
#13
World Triathlon, headquartered in Lausanne, Switzerland, is the international governing body recognized by the International Olympic Committee.
#14
In draft-legal triathlon events (including Olympic races), cyclists are permitted to ride closely behind competitors to conserve aerodynamic energy.
#15
In non-drafting triathlon events (such as standard Ironman races), drafting behind cyclists is illegal and penalized with time infractions.
#16
The Mixed Team Relay, introduced to the Olympics at Tokyo 2020, features teams of two men and two women each completing a super-sprint circuit.
#17
Paratriathlon made its Paralympic Games debut at Rio 2016, utilizing handcycles, tandem bikes, and racing wheelchairs across adapted classifications.
#18
Proper nutrition and hydration strategies (fueling on carbohydrates and electrolytes during the bike phase) are essential to prevent glycogen depletion ('bonking').
Subject Specialist Commentary
Analytical perspective & practical exam advice from the Master10 academic board
A triathlon is an endurance multisport race where athletes complete three sequential stages: swimming, cycling, and running. The race clock runs continuously from the starting swim until crossing the finish line. Rapid transitions between legs—Transition 1 from swimming to cycling, and Transition 2 from cycling to running—are so vital that athletes call them the fourth discipline. Originating in California in 1974, triathlon joined the Olympic Games at Sydney 2000.
Sports questions in SSC and State PSC exams test the exact Olympic distance: 1.5 km swim, 40 km bike ride, and 10 km run. Do not confuse this with the grueling Ironman distance, which requires a 3.8 km swim, 180 km cycle, and 42.2 km marathon. Questions also target the governing body, World Triathlon, located in Lausanne. Remember the competition sequence with the phrase: "Swim, Spin, Sprint."
