Progress?

So last week was my rest/test week again. I'm pretty pleased with my progress in the swim and run, but the bike fell apart. My coach thinks something may have been amiss with the equipment or testing set up.
Here are results from the last two time trials.
Swim (1000 yards):

Date	Time	T-pace	Difference
3/29/2007	18:37.5	01:51.8	00:02.7
3/1/2007	19:04.8	01:54.5	00:04.8

Bike (computrainer):

Date	Minutes	Max Exertion	Max Power	Max HR
3/30/2007	8	18	210	175
3/2/2007	10	19	250	173

Run (2 miles):

Date	Distance	Total Time	Pace	Avg HR	Max HR
4/1/2007	2 mi	17:46	8:52	173	181
3/4/2007	2.01 mi	18:41	9:18	159	179

So...what the f*&! happened in my bike test? I have a hard time believing that I totally bombed the bike test and showed reasonable improvement in the other to.
Good news is the weather has decide to think about warming up. It's still cold, but actually saw some temps in the 40's last week, so maybe there is hope.
The biggest problem these days is overcoming some inner demons. But, what doesn't kill us only makes us stronger, right?
Making it happen....
