BVC Structured Workout - 2 days

Yesterday was motor pacing. today was Whistle drills...

I put on a smallish gear tonight, 51x16 (about 84")... 

Felt like a sewing machine... The Whistle Drill was mostly short sprints and one set of take-a-lap... Which where are  really difficult (well for me) on that small a gear... I found it tough to spin fast enough to get speeds up... 

When I did get speeds up my heart rate went up and I got out of breath quickly... And how humiliating .... "C" racers where out sprinting me :-)
