6 x 400 Metres

Recoveries: 90s – 120s (should roughly match the time it takes to do the 400 metre rep)

Adding to the distance again to improve the speed endurance. Don’t worry if the pace drops a little. In fact I would encourage that here to ensure you keep the speed consistent for the whole rep. Dig deep. These sessions are tough but it’s where our fitness improves and the real magic happens.
