Laura, who recently married fellow cycling star Jason Kenny, says diet is important and now plays a huge part of her life.
At the World Championships in 2013, she won a silver medal in the omnium and it happened three years in a row and that was when she realised she didn’t want another silver medal with Rio on the horizon.
In 2015 her team looked at what they could change - was there something in the training programme? So Laura decided it was her diet and she enlisted a nutritionist's help and started to eat a lot more healthily.
Laura said: “I like to keep it as natural as possible, and I'm allergic to most things anyway. Milk is key for me and was important throughout the Olympic process. I have a pint after training and another before bed. I've performed better on my bike as a result and I feel better in myself as well and I honestly never thought I would.
“But I still eat chocolate - I can't give that up.”
