At the conclusion of every Cross Country Team Banquet, the Senior Varsity letter blanket ceremony begins. Cross Country is the only sport at Northside that follows all of the traditions of the first Varsity letter ceremony.

 In 1903, University of Chicago Track Coach Amos Alonzo Stagg, among other things, invented numbers on uniforms, and the Varsity letter, and the first Senior Varsity letter blanket ceremony took place at the International House in Chicago. For over a 100 years, the traditions from the first Varsity letter ceremony have been followed. In 2004, Jon Gordon came from the University of Chicago Track & Field program to take over the Northside Cross Country program, and brought with him the traditions of Amos Alonzo Stagg and the Varsity letter blanket ceremony to Northside College Prep.

 The ceremony begins with the Team Captains holding up the blanket of each Senior athlete who earned a Varsity letter during their high school Cross Country career, and display the blanket to the crowd before it is placed on each athlete. The Varsity blankets are custom made, and each one has the athlete's name, Cross Country, and Northside College Prep, embrodied on it, along with a Varsity letter "N", and a Silver Star for each year the athlete earned a Varsity letter in Cross Country, and a Gold Star for each year the athlete was a Team Captain for the Northside Cross Country Team. The Senior Varsity letter blanket ceremony is one of the highlights of the Northside Cross Country banquet. It is the highest honor a Senior athlete on the Cross Country Team can be given at the Banquet.

  The Northside Cross Country Team is the only sport at Northside College Prep that awards Varsity letter blankets. To earn a Varsity letter in Cross Country, a Northside athlete must finish among the Top 7 athletes on the Team in a Varsity Race (Top 8 for races held in Wisconsin), or run a minimum of 500 Miles in the summer for an automatic Varsity letter, or be a Senior Captain for an automatic Varsity letter.
