The concept of fast

I have worked on this over the fall into the holidays.  This entailed pushing myself on the treadmill with interval training.
I havent run much since the holidays.
I spent a good part of this month getting back in the saddle.
So now I am back to some focus.  And the newest layer to add to the mix... SWIM fast!
I was back in the water yesterday.  And to my surprise even with such a long break my 100 yard swim time comes in at just over 2 minutes.  Then I remembered, I need to add the same philosophy of sprint work into my swim.
So I did some fast laps in my 800 swim yesterday.
Todays swim will just be to swim.
There is going to be a bike in there too.
