Cycling and triathlons are both disciplines that have an extreme cardiovascular component. Events usually cover many hours and participants require 100 – 200% more than their normal daily caloric intake when participating in these events.
Unlike most sports where supplementation generally focuses on after the event and training, these events are so long that supplementation is often utilized before the events begin, which helps sustain the athletes through their events.
Athletes in cycling and triathlon events do little resistance training, any resistance training is generally restricted to higher repetition muscular endurance work and due to simple efficiency needs, athletes generally stay as lean and light as practically possible. Most training is of a consistent cardiovascular nature, with a focus on monitoring hear rates and increasing Vo2 max.
