Reverse Brick?

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!
