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.
The translator motion of the cutting tool is produced by the kinematic chain of the feed motion, whose first unit is the spindle and whose last unit is a rack-and-gear drive in the case of turning or the kinematic pair of the feed screw and split nut in the case of threading.
