 // ==== Challenge 1: Use .forEach() ====

+    fullName.push(`Name: ${runner.first_name} ${runner.last_name}`)

 // Now that you have used .forEach(), .map(), .filter(), and .reduce().  I want you to think of potential problems you could solve given the data set and the 5k fun run theme.  Try to create and then solve 3 unique problems using one or many of the array methods listed above.
