Row 4321m 
Rest 30 seconds
Row 1234m

A: 4321m time (19:28.9)
B: Total Time (24:45.9)

The brief rest will allow you to mentally reset and attack the second half of this workout. Turned the drag down (98) to keep the flywheel moving. Held a moderate pace throughout most of the row, working up to a sprint during the last 300 or so meters each interval.
