Heptathlete Jessica Ennis put through her paces
BBC's chief sports writer Tom Fordyce gets exclusive access to a rigorous training session with Britain's top heptathlete Jessica Ennis and her coach Toni Minichiello.
Minichiello put the 25-year-old Ennis through her paces ahead of the World Championships in Daegu, South Korea at the end of August.
The Sheffield-based athlete told how she copes with the "indescribable" pain after a particularly difficult work-out and what music she uses to distract her during a race.
