B.B Sting - For Rounds and Reps 
AMRAP 17
200m SkiErg
Rest 3:15
Pacing: Send

DF 80

The seemingly inconvenient rest period is meant to entice you to hold a "faster than 4:00 per interval pace" which should be very doable assuming you can recover well enough to truly send each effort.  Warmed up with the DarkHorse 10 minute build then hit this effort. Kept the rate high and the drag on the lower end during each interval. Finished the fifth round with 18 seconds remaining.
