Half Fast swim

Say "Half Fast swim" fast, and that about sums up today's workout.
Got up at 0420 and was in the water at 0543:

1000 free easy
Masters workout:

300 swim, drill, kick
500 - 500 free @ 80%, long efficient strokes

500 pull @ 85%
500 - 10 x 50's free fast (95%) on 1:00 (held :32)

200 easy 

This workout came from Andrew and I loved it.  I was feeling like a putz when I got in and did the 1000. It was slow and I felt like an old fart.  But then the 500 sets really got me going and I was put into first position in my lane with Kris and Scott.  Had to step up.  

 Then stayed after and did:
1000 pull
1000 kick with fins


6000 yards total in 1:58
Feeling very sluggish!  Getting up at 0400 is starting to wear on me.  Tomorrow evening is the cold water swim.  Looking forward to it.  This weekend I'm doing a 20 mile hike with the scouts so I'll probably not do a swim this Saturday since I'll be wasted from that hike!
