[7] A large lead group of 22 athletes were together at the end of the cycling leg with a gap of over a minute and a half over the rest of the field.

A NOC with an athlete who won one of the five continental championships (Africa, Asia, Pan America, Europe and Oceania) were given one place in the event.

Additionally, three places were available for the NOC of the medallists at the International Triathlon Union (ITU) World Qualification Event.

[2] The cyclists first rode down Serpentine Road towards West Carriage Drive before changing direction and cycling to Hyde Park Corner.

The course then quickly turned left towards Hyde Park to go past Buckingham Palace on Constitution Hill.

[2] After passing Buckingham Palace, the cyclists turned and went back towards Hyde Park and eventually crossed through the transition area before starting the next lap.

[3] Richard Varga (Slovakia) led early in the swim leg and held the lead to come out of the water first.

[11] Hall led a group of seven; Line Jensen (Denmark), Mariko Adachi (Japan), Pâmella Oliveira (Brazil), Claudia Rivas (Mexico), Laura Bennett (United States) and Jessica Harrison (France); out of the water.

[11] In the early stages of the bike leg, Hall slowed the leading pack down so that her teammate Helen Jenkins (Great Britain) could catch-up.

[18] The lead pack joined with the peloton at the end of the second cycling lap to form a 22-women strong group.

[8] Due to overnight rain the roads were wet and multiple athletes crashed on the bike leg.

[20] Two athletes in Kathy Tremblay (Canada) and Emma Moffatt (Australia) had to withdraw from the race due to crashing.

[22] They were Nicola Spirig (Switzerland), Lisa Nordén (Sweden), Erin Densham (Australia), Jenkins, Sarah Groff (United States) and Andrea Hewitt (New Zealand), Ainhoa Murúa (Spain) and Emma Jackson (Australia).

[19] Groff then rejoined the group at the very start of the final run lap after being dropped earlier on in the race.

[11] Groff finished fourth with Jenkins fifth, Hewitt sixth, Murúa seventh and Jackson eighth.

[11] After the race, Nordén and the Swedish Olympic Committee appealed against the result in the Court of Arbitration for Sport (CAS).
