This achievement is pretty simple. You need to run for 1,000 yards after a catch, kickoff, etc. This is not total yards gained, but the yards gained while running.
A few notes to help. The faster you run in place the faster you move, although I don't notice a significant difference. If you jump before you are about to be tackled, you often will juke the defender, use that to string together some long runs.
You should easily get this achievement while going for the other football achievements in the game. Although that is not true for all as some have commented below. Keep playing and it will unlock.
