Pick TWO of the following: 

  1. 1000m Hypoxic Pyramid Swim*
  2. 1 Hour Ruck, 50-60 lbs load, how far do you get?
  3. 1 Hour Bike, hills, moderately intense setting

*Hypoxic pyramid- Swim one lap breathing every 3 strokes.  The next lap breathe every 5, then every 7, etc.  Go till you fail, then work your way back down.  Keep going till you've done 1000m total.  This is a GREAT psychological and cardiovascular challenge.
