Mt. Madonna Challenge


Annual Bill Flodberg Mt. Madonna Challenge

In his 75 years, Bill wore many hats, and he wore them with equal passion. Bill was an avid runner; during college, he ran for UC Berkeley; later, he ran and trained on the roads and trails in San Martin and Gilroy, and he raced competitively well into his 70s. In addition to his personal running accomplishments, Bill encouraged runners and running as a Cross Country Coach at Gavilan College, as one of the founders of the Gavilan Joggers and Striders Running Club, through his “Running Man” running column, and as an organizer and director of several local races, including the Mt Madonna Challenge.

Bill was also a longtime supporter of the South Valley Symphony and other arts groups, to which he brought the same passion that he had for running.

Bill was a quiet person, yet he proved that one man can make a tremendous difference for the lives of those in his community. Thanks to Bill, thousands of people were enriched by his efforts to encourage music and the arts. And thanks to Bill, thousands of people in the running community have benefited from his example, encouragement, and advice.

The South Valley Running Club is proud to continue Bill’s legacy by dedicating this race, in it’s 42nd year, in his name. The Bill Flodberg Mt. Madonna Challenge is a fitting tribute to a man who spent his life improving the lives of others.
