Para triathlon Sport Classes:
World Triathlon Para triathlon has implemented an evidence-based classification system
to group impairments into sport classes according to the extent of activity limitation they
cause the athlete when performing in the sport of para triathlon;
There are nine (9) sport classes.
(i) PTWC1: Most impaired wheelchair users. Athletes must use a recumbent handcycle
on the bike course and a racing wheelchair on the run segment;
(ii) PTWC2: Least impaired wheelchair users. Athletes must use a recumbent
handcycle on the bike course and a racing wheelchair on the run segment;
(iii) PTS2: Severe impairments. In both bike and run segments, amputee athletes may
use approved prosthesis or other supportive devices;
(iv) PTS3: Significant impairments. In both bike and run segments, the athlete may use
approved prosthesis or other supportive devices;
(v) PTS4: Moderate impairments. In both bike and run segments, the athlete may use
approved prosthesis or other supportive devices;
(vi) PTS5: Mild Impairments. In both bike and run segments, the athlete may use
approved prosthesis or other supportive devices;
(vii) PTVI1: Includes athletes who are totally blind, from no light perception in either eye,
to some light perception. One guide is mandatory throughout the race. Must ride a
tandem during the bike segment.
(viii) PTVI2: Includes athletes who are more severe partially sighted athletes. One guide
is mandatory throughout the competition. Must ride a tandem during the bike
segment.
(ix) PTVI3: Includes athletes who are less severe partially sighted athletes. One guide
is mandatory throughout the competition. Must ride a tandem during the bike
