First ride with the 305

So, I had my first ride with the 305. I'll need to play with its position. It was hard to see the screen at times -- it could use an antiglare screen but maybe some polarized sunglasses would work. I had the display set up to show 8 different things which is probably too much because of the small size of the display. Happy to say that the heart rate monitor worked great. I didn't even notice it on me while I rode.
I'm working on my sprints and I did two 5 minute stretches where I sustained over 20mph (and no, it wasn't downhill). I averaged 16mph and made it home in just 30 minutes. The 305 said I burned 670 calories which is right on par with DietPower. Maybe I'll lose another 1/2 pound tomorrow!
