Workout critique

I'm doing a sprint race in late Feb, and I've just started the following program which will take me to race day.

This is how my week looks:
M: short run, weights
T: long swim
W: short ride, weights
T: short swim
F: medium swim
Sat: long ride

So I'll be doing 3x swimming, 2x running, 2x riding, and 2x weights per week.

This is what I am planning to do for my weights sessions:

Monday - squats, step ups, calf raises, pulldowns, rows, chest press, shoulder press.

Wed - squats, step ups, calf raises, crunches, alt crunches, bridge

So I'll be working legs 2x per week, and upper body and abs 1x per week only (this is because I'm swimming 3x per week and don't want to overtrain upperbody and abs).

Any suggestions on what rep ranges to use? I was thinking of doing 6-8 reps for the Monday and 12-15 for the Wed workout, how does this sound?

Also, how many sets would be sufficient? I was thinking 2-3 max.

Any changes you'd recommend?

Thanks a lot
