How a para triathlon works

1. Para triathlon is a swim, a bike ride and a run, in that order, for athletes with an eligible impairment.
2. There are three groups of classes: wheelchair users (PTWC), standing athletes (PTS) and vision impaired athletes (PTVI).
3. Wheelchair athletes ride a handcycle and run in a racing wheelchair. Vision-impaired athletes race with a guide, tethered in the swim and on a tandem bike.
4. Where classes share a medal event, less impaired classes have a set time added to their finish, so the first across the line may not win.

How long

Major events are sprint distance, with a two-hour limit.
