She expects to finish her quest by the time she is 15. Winter is also on a mission to raise awareness and funds for prostate cancer research, a disease that claimed her father. She will be the youngest runner ever to tackle the Antarctica Marathon. Lynn McLernon, MD ( Upper Tantallon, Nova Scotia, Canada ) – Lynn is running the Antarctica Marathon to celebrate her five-year cancer free status. She was 39 years old when she found hard lumps in her armpit. As a doctor, she knew that she was feeling lymph nodes and learned that she had an aggressive cancer that had actually not only given her multiple breast cancers, but had eaten through her lymph nodes. Lynn's treatment included a double mastectomy, chemotherapy, radiation and herceptin, a relatively new medication. Lynn is running to raise funds and awareness for breast cancer research. If Lynn had been diagnosed a few years earlier, before herceptin was developed, she believes that she would not have survived. This will be Lynn's eighth marathon, but the first since her cancer diagnosis five years ago. The Antarctica Marathon and Half Marathon's official charity is Oceanites, Inc., a non-profit organization that researches the impact of tourism on Antarctica's environment.
