I considered today’s the Hard medley lesson menu from morning during about two hours to be worried what kind of menu instruction.

Up) 200m,
Kick) 400m, OB-Medley order
Loosen) Easy 50m,
SW1) 400m = 100m * 4times,
   Each 100m Medley order Right, Left, Swim and Free

SW2) 1050m = 350m * 3times,
   (1):Cr, IM, Cr, (2):200IM, Cr, Cr, (3):Cr, IM, Cr

Down) Free 100m,

Total swimming distance is 2,200m during 50minutes!!
Can you swim this menu?
