They can't all be good

Long day at work + Late dinner = terrible swim.

I was only able to get in about 35 minutes last night due to being at work until late, and I had one of the worst swims of this training period. All the workouts can't be great and a bad swim is better than no swim. I almost got out of the pool after 15 minutes because it felt so bad, but I forced myself to stay in the pool and finish out the time. There's no "stepping out of the pool" on race day.
