More than 5,000 people attended DU's DebateFest, and an additional 1,000-plus attended the debate itself at the University of Denver.

Debate Day: By the numbers

It might look effortless, but hosting the first presidential debate at the University of Denver on Oct. 3 took nearly a year of planning, preparation and work by scores of students, faculty, staff, alumni and University community members working side-by-side with city, state and federal officials, as well as the Commission on Presidential Debates.

More than 1,000 guests were in the audience in the debate hall, including 297 University of Denver students. Millions of people around the world watched on television and online.
