A Colorado woman who’s worn out 25 pairs of shoes walking around the planet to raise awareness about breast cancer is starting the final leg of her journey in Iowa today (Saturday). Polly Letofsky says it’s been an amazing adventure and she’s almost home. Letofsky left her home in Vail on August 1st of 1999 and headed west. She’s now gone through 22 countries and 13-thousand miles. She’s only taken one break, the winter respite she’s just coming off of, which she took due to the danger of walking through the cold weather, ice and snow of the Midwest. She’s leaving a hotel in Keokuk (kee’-ah-kuck) this morning and will head west again, though Missouri, Kansas and back to Colorado, returning home on August 1st, five years after she started the trek. Letofsky explains her motivations.She’s worked with breast cancer organizations in each of the nations she’s walked through and all money raised stays in each of those countries, for education and awareness. The 41-year-old Letofsky says several close friends have had breast cancer and she was subject to some medical mis-information early on, which cemented her motivation to take the hike. Letofsky says she went in for a mammogram and was told by a doctor -incorrectly- she didn’t need to worry about breast cancer since it didn’t run on her mother’s side of the family. She later learned every woman is at risk, regardless of family history. Letofsky is a Minnesota native and has chronicled her journey at “www.globalwalk.org”.
