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 term translation simply means that to align the frame B with the frame W, all you have to do is translate the frame B by some amount. However, for robotics, we are interested in the motion of rigid bodies, and so we have a more complicated configuration. A translation is no longer enough to describe the configuration of a rigid body. A rigid body is one in which the relative distances between the particles which make up the body are constant, no matter how the body moves.
