Here in Minnesota the snow is almost gone, so only a few weeks more. My first season last year, I remember using lower gears with a lower cadence. I think thats where the fixation to cadence is coming from now. Assuming the same cadence - if my computer shows that my MPH goes up when switching gears, Im obviously working harder at the same cadence. Im working on intervals now, but they aren't very structured yet - more along the lines of - push harder for 2 minutes so my heart rate gets to about 178, rest for 5 unitl heart rate comes back down to 165 ... repeat 3-4 times.

There is a 100 mile ride coming up at the end of April I want to do well on - but I think under 5 hours is pushing it for only my second century ride.
