Triathlon is a multisport that includes swimming, cycling and running - a few of the best sports for fitness!

Every athlete taking part competes for the fastest time overall. This time includes each sport in the race, as well as the time it takes to transition between them.

Her gold medal was decided by a photo finish, as she and Swede Lisa Nordén finished simultaneously.
