Triathlon is the individual sport of the 21st century. The competition, which is quite new, involves the sequential completion of swimming, cycling and running.
The three disciplines have to be completed sequentially, without a rest, and the transitions between the discimplines are also timed. If drafting is allowed at a competition, a competitor may make use of the slipstream of the other competitor(s) cycling before him/her. If drafting is not allowed, competitors have to keep a given distance behind one another.
