oh and a quick question - do you wear a HR monitor all the time, is it the regular Garmin one that goes around your chest? I have one which has been sitting in the very bottom of my running stuff drawer for a year since the last time I tried it, I got all sorts of weird, claustrophobic, slightly panicky feelings...(to keep it tight enough to not fall down and keep the contacts, it was tight enough that it felt like my breathing was much too restricted. of course, i also feel claustrophobic in tight turtlenecks and wetsuits...any advice?)
