Alarm Fail

You'd think after 41 years on this planet, I'd be smart enough to be able to set an alarm clock properly. You'd be wrong. Er, at least you'd be wrong last night. I managed to set mine for 540am instead of 440am, making it a bit difficult to be at my training group's long run by 6. I really wanted to make this one because a) I need to get my miles up before Disney, and b) I wanted to use my discount coupon at Fleet Feet to pick up some new running sunglasses. The cheap pair of Tivolis I bought at a marathon expo last winter have broken twice on me, so instead of getting a third lens for them, I'm going to spend the extra money and get a higher quality pair. Anyone have any suggestions or recommendations?
