We'd never thought much about the beauty regimes of athletes - that is, until London won the 2012 Olympics and suddenly every member of Team GB got a contract with some form of beauty product.
Track and field athlete Jessica Ennis is currently one of the spokespeople for Olay Essentials and she talked to them about her beauty routine during training while she was getting ready for the Cosmopolitan Ultimate Women of the Year Awards recently.
The 26-year old reveals that she always makes sure she uses Olay Essentials cleanser after training to get every trace of grime and sweat from her face, as well as Olay Essentials moisturiser, "which is really light - so you don't feel like you've got too much on when you're training".
Jessica admits her usual look for nights out is eyeliner and some lipgloss but she leaves for the Cosmo awards a much more glamourous version of herself with smokey eyes and a really cool side ponytail. Check it out above.
