We did this set in SCY based on athletes’ best times. We did 300 yards easy between rounds as recovery and the set was presented 1 part at a time. The first 10 the goal was to be within 10 seconds of a lifetime best, on the second round 9, etc. These were the goal times for the lane leaders. Athletes not going first in the lane were expected to be a second faster due to the drafting effects. Last 4 fastest possible average with fins. We got some outstanding results with this set!
