Hi Paul,
I gave this a go yesterday - it still seems to work fine though, it works as far as I can tell - it still gives me the overall average at the top of 'Totals' in TC, but below that I get the individual breakdown for each miles effort, which is rather useful.
Theonly slight annoyance is that I get the countdown beeping at the end of everymile, have to see if I can switch that off somehow.
Also for the first time started training in HR zones as opposed to bpm or %, and it worked a treat, this little device continues to amaze me!
Cheers
Dan
