60A current drain on supercapacitors in series?
Quickly simulating what you described, it looks like you will run out of power way before you cross the finish line. 6x 2.7V 60F capacitors will hold 1300 J assuming they're charged at their nominal voltage. The EDF you linked will draw way too much power for your capacitors to handle.

They would indeed charge/discharge at the same time, so to supply 60A you would need 3 parallel lines of capacitors.

So, without even considering charge/discharge complications, this doesn't seem doable for a race lasting more than a second.
