More than a million runners, joggers, walkers and spectators have gathered over the years to create a spectacle that defies description. That has to be the BolderBOULDER!

Get in the spirit with a one time only event to celebrate the BolderBOULDER’s 40th year milestone. The 40 Years Bold celebration brings together legendary runner Frank Shorter and co-founder Steve Bosley to speak about and sign their new book, 40 Years Bold: Oh Yes, You Can.

This fascinating book highlights all the founders, the memories, the record breaking finishes, the spectators and more. The beautifully bound, 160-page story, celebrates 40 years of running joy.

The book signing event takes place at the Boulder Theater, 2032 14th Street in Boulder on Saturday, May 19. Doors open at 6:30 p.m. and the celebration starts at 7:30 p.m. Tickets are $15 and can be purchased online at
