I would be interested to see if there is a correlation between your 5k pace (for example 6 minutes per mile) divided by 2 (3:00) equals a 3 hour and 00 minute marathon time. Discuss.
It's the basis of Yassoo 800's i.e. running 800's at 5k pace in the same time in minutes and seconds as your target marathon pace in hours and minutes.
