Workout last night

Last night's swim workout was pretty challenging but I found the main set to be quite fun.
We started off with 12x25 on :40 doing the following:
1 swim butterfly, 3 butterfly drill
2 swim butterfly, 2 butterfly drill
3 swim butterfly and 1 butterfly drill.

Overall that set didn't seem too bad for a warmup.
The next thing we did was 7x100 on 1:50 choice or pull (needless to say I did easy backstroke for this)

The main set was as follows:
4x100 IM on 1:50
200 IM on 3:40
4x100 IM on 1:40

This set actually was pretty tiring. Fortunately, I made all the intervals on the last set of 4x100 despite the fact that I had to swim around people a few times as I was going on a faster pace time. I was averaging between 1:32 and 1:38 on all the 100 IMs for both sets and I did a 3:14 for the 200 IM.

We finished off the practice with 12x50 pull/choice on :55. That was not too bad and I was able to do them easy backstroke without any problem.
Total for this practice was 2600m. It's pretty good, definitely one of our longer practices to date. It's good that we're having these practices now so that we can get in shape for provincials.
I don't think I'll head to the gym today even though I have time since I seemed to have developed a cold and am feeling a bit sluggish today. I think I'm going to take it easy and go on Thursday instead.
