Completed first half mile swim!!!!!

So today I went to the pool with the intention of trying to swim 14 laps. A half mile/ 800 meter swim is equal to 18 laps. I finished all 18 laps and maybe 19 laps. I lost track and went low to be safe. i also finished the swim in about 45 minutes. I am super excited. I need more practice and would like to be able to easily swim 22 laps by May 9 to prepare for the open swim but I am thrilled so far. I also need to remember to stop swallowing the pool water.
