Q: My training partner likes to sprint at the end of runs. Is that safe?

A: ‘Producing maximum effort when your body is fatigued risks injury, as tired muscles strain easily,’ explains running coach Ryan Warrenburg.
‘If you want to end a workout with faster running, do strides. These controlled efforts differ from sprints as you gradually ramp up speed over 20-30m, hold it briefly, then slowly decelerate over 20-30m, allowing the muscles time to adapt to and recover from the change in gear.
Save sprinting for speedwork, and be sure to sandwich those sessions with 10 minutes of easy jogging to warm up and cool down.’
