I thought I might share a deceivingly tough sprint set that I drop on my home programme 2-3 times per season.
Depending on what you are looking for , I have sometimes only timed the 50’s or just the 100’s.
On one occasion we turned off all the pace clocks and simply went off whistle on each interval, focusing on effort level and technical aspects such as the efficiency of breakouts under pressure.

Love this!!!! Especially turning off the clock and relying on your mind. Great stuff!
