Have you ever completed a marathon 26.2 mile run?

I have registered to run a half marathon in mid August and I might do another marathon two weeks later in late August. Half marathon and marathon only two weeks apart.
A sub 4 hour marathon would be my ultimate personal fitness goal.

Anyway how do you improve on running hills? Running on flat course is relatively straight forward but hills (downhills and upwards) require a lot of strength and endurance to overcome.
