Time to test your comprehension skills! You'll hear a challenging conversation that includes lots of uses of 'hit the ground running' and 'fall behind'. I then analyse the conversation in-depth and look not only at the vocabulary but also the pronunciation. This will help you understand natural English as it's spoken in the real world. Then you'll hear the conversation again to see how much better you understand the second time round. More info: http://keyteenglish.com/es/hit-the-ground-running-and-fall-behind/
