I guess I did a reverse brick for tonights workout. I went to Washington park, when I started my run I realized my Garmin was dead, forgot to charge it. So with out modern technology I did my tempo run a different way. I broke the park up into sections and ran a fartlek every other section. I don’t know how fast, but I was breathing hard when I finished 5 miles. After the run I went to fit club and swam 1.5 miles. The water felt great. The last half mile I was pretty tired. I still think it was easier than a bike- run brick!
