I’ve been a runner for a long time. I trained for (and ran) the 1994 Los Angeles Marathon. I’ve run 5K races, half marathons and relays for full marathons up here in Alaska, too. I find that running gives me the best bang for my buck: All I need is a pair of running shoes, some appropriate clothing (it gets cold up here), and some music to keep me getting out there.
Recently, though, I’ve been playing with a new bit of gear: the Pear Sports heart rate monitor, paired with a set of earbuds engineered to stay in your ears while working out, plus a pretty fantastic mobile app to make sense of the heart rate data.
