UPHILL ENDURANCE

Run up a hill for 60-90sec. Walk down. Repeat 8 times

HOW Find a tall hill outdoors or set a treadmill to an incline. The hill should be steep enough to make running up it feel like a nine out of 10 in terms of effort.

WHY Getting used to uphill running will increase your stamina and prepare you psychologically to go all out in the home stretch.

“It will be painful in the final 400m, and this gets you familiar with that feeling,” Mackey says.
