I've been using the auto-lap marker at 1 mile intervals - it just gives me a little "beep" at each mile - and I find it oddly encouraging! But I guess I can turn it off and add the laps after the fact (like SK). Dianyla, I am so bad at remembering to add the laps before an after each hill!

I now have several questions to ask Polar tech support:
1. How do they calculate time spent climbing, flat and descending?
2. Do cadence and speed averages take into account time not moving?
3. Why do I get the BSOD every time I remove the USB infra-red thingy? (Even after uninstalling and reinstalling the Polar USB drivers)

Again, thanks for the great suggestions! I have a huge amount of project work, and all I want to do is mess around with this stuff! But I will send an email to Polar today, and maybe snoop around in BJ ...
