Hi TC, I have used in the past 7x100m round the track with 50m walk back recovery, so I could use that again for them as their “long session” to begin with. Then after a few weeks of that try something along the lines of what KK was advocating i.e. using 150m + down the clock from 60m. They are at the moment doing 3 sessions of tempo on grass with bodyweight exercises immediately afterwards. The other sessions will be as stated, e.g. Tuesday 2x4x15m followed by multi jumps circuits. Sunday med ball for power + general conditioning. The longer track work done on Thursdays.
Question for both of you - what intensities would you be expecting the respective sessions you suggested to be ran at.
