OK, Katy it is! The best way to get people to do something in a chat room like this, is to tell them not to!
Can't you run with a garmin GPS? Your "guessed distance" boasts and "map my run distance" boasts have both been proved wrong. GPS boasts would be fine - had you boasted about a 21 minute 5k rather than a sub 20 5k, it would have been perfectly defendable.
AND you could see how you were improving, and tailor your training. For the mileage you do, you should be going under a 3 hour marathon. No need for a schedule, but better feedback data might be useful!
