4/9/17: completed threshold heart rate training today. Over the past week I did a swim (1000 yds), run (5K) and bike (30 min) for max distance or fastest time. These turned out about as expected: running is my best discipline, biking intermediate and swimming is worst. But it was very motivating to do the testing and did teach me a lot about how I train and race. First, my max HR is higher than I realized, about 170 bpm. Second, I'm not in as bad of shape as I thought. And third, it's cool to have someone else tell you what to do, rather than feeling like you are randomly working out without a plan!
