Key dates: Aug. 4
Venue: Hyde Park.
Big story: There has been one American to reach the medal podium since the sport made its Olympic debut in 2000. Susan Williams survived a crash into a soft barrier on the opening cycling climb to eventually take third in Athens in 2004. The second U.S. medal could come from a relative novice, Gwen Jorgensen (above), who could take advantage of the flat course. She has gone under 16 minutes in the 5K -- the Olympic event is 10K (6.2 miles).
Top U.S. prospects: Laura Bennett, Sarah Groff, Jorgensen
Others to watch: Helen Jenkins (Britain), Andrea Hewitt (New Zealand), Paula Findlay (Canada).
Little-known fact: The only woman to compete in all four Olympic triathlons is Anja Dittmer of Germany, who will turn 37 in September. Her best finish was 11th place in Athens in 2004.
