There is typically a lower age limit; which can vary from race to race. In some triathlons, heavier amateur athletes may have the option to compete against others closer to their own weight since weight is often considered an impediment to speed. As an example, under USA Triathlon rules, "Clydesdale" athletes are those men over 220 lb (100 kg), while "Athena" athletes are women over 165 lb (75 kg). Other races and organizations can choose whether or not to offer Clydesdale- and Athena-type divisions and set their own weight standards.
