We all know that running and exercise can often aid a good night's sleep, but how can sleep aid our running?

This week Jenni is chatting to chartered physiotherapist and sleep expert Sammy Margo.

Jenni and Sammy chat how much sleep is enough sleep, how the position you sleep in can change your dreams, the benefits of a nap, tracking your sleep and the dreaded snooze button.

Run and sleep well!
