But to run faster over 26.2 miles, you have to increase your endurance. If youâre a 41 year old woman and you can run a 4:00 marathon (or about 9 minutes per mile), an ambitious goal would be to qualify for Boston in 3:45 (5 minutes under the BQ time).y the end of my Philadelphia training, my long run was 22 miles with 3 x 3 miles during the second half in 18:48, 18:05, and 17:46 with a mile recovery in between each. I ran 15 miles with 8k at progressively faster than marathon pace.
In a translation, every point of the object must be moved in the same direction and for the same distance. When you are performing a translation, the initial object is called the pre-image, and the object after the translation is called the image. So, in the picture above, the rust-colored item is the pre-image, and the blue item is the image.
movements up and down change the $y$-values of points; transformations that affect the $y$-values are intuitive. (e.g., to move up $\,2\,$, you add $\,2\,$ to the previous $\,y\,$-value) movements left and right change the $x$-values of points; transformations that affect the $x$-values are counter-intuitive.
