A little tip, set the auto pause speed at something like 3-4 mph, because sometime whilst at junctions you do get a few wayward readings, the sp/cadence sensor helps with this as it is slightly more responsive, though being wireless there is a little lag (unlike wired).
As for the H.R. well in Jan my Avg Max H.R. ised to be about 167 this month its 153 (though I think thats a little low as I forgot to put it on twice) last month it was 159, and my rides are technically more difficult, having said that my cadence has gone down a touch from about 80 to 77, but I am using a longer gear 62" compared with 57" which i think is due to the climbing, I have been doing, at alot of the time when I am just riding flat roads these days it wont even register in zone1.
The breadcrumb trial works well enough once you get used to it, the 500 (not sure about the 200) will also give you turn warnings if the right software is used to plot the route, rwgps for instance, though the V.P. doesnt work using that sites software, well it does, but at about twice the time it will take you, so you always win, with sporttracks you can even make it warn you in advance of turns (but you need to pay for this and the plugin).
