PHOENIX -- Endurance athlete and motivational speaker Croix Sather is running the equivalent of 100 marathons in 100 days.

He sat down with Scott Pasmore Tuesday morning to talk about his book, "Dream Big, Act Big," and explain why he is running 3,100 miles in 100 days.

"The secret to life is the experience of leaving a lasting positive impact on the world," Sather said on his website.

Sather will be giving a motivational talk Wednesday, March 9, 10:30 a.m.-11:30 a.m., at South Mountain YMCA, 222 E. Olympic Drive, Phoenix.
