Think running a marathon is crazy? How about climbing 598 Steps, 23 Floors, 422 Feet?! This annual race serves as a powerful reminder for everyone to handle their lungs with care. Even local bookseller Ken Sanders and several of his employees are getting in on the action. Sanders is surprisingly fit these days, enough so that supporters believe he has what it takes to Tackle the Tower. Sanders is one of the top fund-raisers this year! So get involved, or just come down to the Wells Fargo Building on Salt Lake City's Main Street to cheer on the participants. Proceeds benefit the American Lung Association in Utah. Party to follow. 8 a.m.-12 p.m.
