Typically my worst mile in running is my first and depending on the length of the run the last. Which pretty much sums up everything I take on! Getting started with a project or anything new requires a great deal of discipline. The thought of daunting tasks are sometimes too much to bear so we/I procrastinate. Procrastinating is just like those annoying leg cramps in the first mile you either succumb and walk or work through it and complete the goal.
After Getting through the first mile you gain momentum and a rhythm and all goes along well. Until the tedium and length weighs you down, and you quit or stall. This is when training and experience will get you through to the end.
Completing tasks requires practice just as long distance running does. So train the same way. Start with low mileage/or small projects and build up until you can complete your marathon…
