This book proposal outlines a book that will tell the inspiring stories of older athletes who continue competing in sports and defying expectations of aging. These athletes include marathon runners, ultramarathoners, triathletes, and others who stay physically active in their later years, keeping their bodies and minds sharp. They serve as an example and inspiration as more baby boomers seek to challenge conventions around aging. The book will share their struggles and accomplishments as they stay in the game through competitive sports.
