Diana Gould is 100 years old and is scheduled to carry the flame in London through the borough of Barnet as a part of the 70-day relay. Gould, who was born in 1912, runs exercise classes three times a week in the retirement home where she lives, according to the BBC.

Gould was chosen to sit for a portrait for the "Road to 2012" exhibition. The exhibition, on display at the National Portrait Gallery, features newly-commissioned photographic portraits of Olympic athletes.

Kate, who has a formal role with the Olympics as an ambassador for Great Britian's athletes, visited the exhibition on Thursday.

Her Portrait Gallery visit marks one of the many Olympic-related events she will take part in over the next several weeks.
