Do you have times on those 60s? I have been following your journal and I understand that “95-100%” refers to effort, not to actual percentage of best time (which is the standard CF method). Do you know what percentage of your 7.00 60 meter best these runs were at?
I’m not asking to criticize you - there’s obviously a multiplicity of ways to skin the sprinting cat - I’m genuinely curious. 2 minutes is just a little more than an immediate walk-back and set back up for me. I would guess that if my 60 best is in the 7.1-7.2 area (I really don’t know), I probably would have a hard time break 8 seconds by the end of the workout. You?
