Cycling is the second discipline in triathlon—after swimming and before running. It has a special role in triathlon, as about 50% of the total race time is spent on the bike, making it the largest part. Another special characteristic of cycling in a triathlon is that, unlike in pure bicycle races, in addition to a good cycling performance great attention must also be paid to the management of leg effort. It is important to minimize the straining effect of cycling on the legs in order to have enough power left for the running part to really be able to achieve a good triathlon time. Because of the importance of cycling and its position in the order of disciplines, proper triathlon cycling training often makes a big difference in overall time. You could win (or lose) the race on the bike. Your triathlon bike training should therefore be carefully adapted to the specific requirements in order to achieve optimal results and to avoid unwanted surprises during the triathlon itself.
