Pedometer incorrect..pretty excited!

Ok so I posted this week about being a new-ish runner and entering a 9K and blah blah. Well last week I started running and ran supposedly 1.15 miles and was rather discouraged by this, especially that it took 19 minutes. Yeah well, my pedometer is either defective or I am and don't know how to work it. I decided to run the track at my old high school tonight instead. 4 laps around is a mile and I ran 7 laps and the pedometer said 1.05 miles! NOT! So, I really ran 1.75 miles in 14 minutes! So I'm running an 8 minute mile, not a 16! Pretty excited right now. I KNEW something was off, I knew I could run a mile under 16 minutes! On that note, anyone have a reliable pedometer to recommend??
