The event that includes both aerobic and anaerobic activities is known as a triathlon. Triathlons typically consist of three disciplines: swimming, cycling, and running, completed in succession. Participants must switch between activities rapidly, requiring both stamina and strength. The aerobic aspect is emphasized during the longer segments, like cycling and running, while swimming may involve anaerobic bursts when sprinting. Triathlons test competitors' overall fitness, as athletes must be well-trained in each discipline to perform effectively and reach the finish line.
