Lap Swim: 88 lengths (1.3 miles) in 1 hr

Too tired this morning to get up for a sunrise swim, Ali and I decided to swim in the evening... I felt great starting out but ran out of steam about half way through :-/ Despite the dip in energy, however, I kept going and was able to do 88 lengths in an hour which is the most I have done to date :-)

Here are my lap times:

Here's a chart showing how my lap times compared:
