I'm finally taking the plunge and going to build a pool in the backyard. I want to make it long enough to swim laps, and also work well for 2 people swimming at the same time because my wife also does triathlon.

I haven't finalized a design yet, although I've met with a few pool builders. At this point, based on budget and overall design considerations, the main part of the pool will be 60' long and 8' feet wide, with a wider 16' section in the middle 20'. 4 foot deep on one end of the lap lane and 6 foot deep at the other end of the lap lane. I can post pictures once I get renderings from the builders.

I have concerns about there being a lot of chop in the water with a narrow pool, particularly with two people swimming at the same time. Although I'm hoping the wider portion in the middle will help. I won't be putting in gutters or spill over edges. However, I could make the lane a little wider, say 10' instead of 8'. That would increase the cost, although not a crazy amount.

Any thoughts on how the shape / dimensions of this pool will work for swimming laps? Any changes you would make?

We did look at doing a rectangular pool with a Fast Lane, but only 1 person can use that at a time, and my wife and I tend to swim at the same time. Also, our yard is big enough for a decent length pool.
