Response:
The answer is:  the quick brown fox jumped over the lazy dog
This is a commonly used phrase that includes all 26 letters from the english alphabet and may be useful when practicing typing.  

This can be deciphered by connecting letters offset by 6 within the string.  The first 3 letters with this pattern are "t", "h", "e" forming the word "the".  Spaces must be inferred from common words and word patterns. 
letter   1 -   t
letter   7 -   h
letter 13 -   e

Visually, this can also be accomplished by splitting after every 6 letters, and then reading columns top->bottom, then left-right.  In the example below the word FOX is highlighted using capital letters in the 3rd column.
