Two years ago, Thompson became the oldest woman to finish a marathon. She completed the 26.2 mile run in 7:24:36. She was initially hoping to run the marathon again but due to health issues, she decided to run the half marathon.
Thompson is a two-time cancer survivor and took up running when she was 76 years old. She raised $15,000 for the Leukemia Lymphoma Society.
In March, Ed Whitlock, the Canadian masters runner who broke three hours for the marathon in his 70s and broke four hours in his 80s, died at the age of 85.
