subject: Don't Buy the Polar RS100 Heart Rate Monitor Until you have Seen This Site! [print this page] This heart rate monitor is my first, and is in the middle of my second marathon training season, and has gone with me to five half marathons. I bought it because of the dual timer. I started as a run walker and with two timers, it told me when to run and walk to take a walk break, and then got me back running again. I tuck the monitor underneath the bottom rim of my sports bra, and occasionally it slips down a bit, but mostly the elastic strap, not the actual monitor.
