Treadmills are boring

Did a pump class followed by 3 miles on the treadmill. It took me about 25.45 running the first min at warmup pace and then the rest at about 7mph increasing that to 7.2 about halfway thru and increasing to about 7.5 for the last half mile or so. My goal is to get this to 25 mins ASAP. I'm hoping won't be too hard now I have figured pacing out a bit. I started at 6.5 which was too slow really.
