time trial week

This seems to be time trial week on my ironman training program. There was a swim time trial of 1000m and yesterday's bike ride included a 30 minute time trial. I did that out in Pownal. Today, the run includes a 30 minute time trial. I am going to do that after work (and before teaching at UPEI) Right now, between teaching at UPEI two nights per week, training, working and trying to do yard work out in New Glasgow, I have very little spare time. This morning we had our swim class. The thing I really noticed today is how high my heart rate goes when I start to do the strokes that I am not as good at. (back stroke and butterfly) I can sprint full out doing the frontcrawl and my heart rate is not as high as when I do backstroke at a moderate pace. Its because your body adapts to what it does alot. Tomorrow I think I will run some hills out in New Glasgow for a change and as a bit of practice for Mooseman. The run in that half ironman is very challenging. There are several steep hills that you have to do a couple of times. It is very much like running out in New Glasgow. Friday, I am going to do a long swim and then Saturday- another long bike ride followed by a short run. Sunday, I am going to do a long run. I am noticing that I am loosing weight. I am not sure that that is entirely a good thing because it is early in my ironman training to be loosing weight.
