Sam Murphy is a journalist, author and running coach. She has written for numerous newspapers and magazines over the last 20 years, and pens the enduring Murphy's Lore column in Runner's World magazine. As a long time runner, Sam has raced a variety of distances from 5Ks to ultras, and she earned her degree in sports and exercise science. Sam and I discuss the common mistakes and misconceptions that can complicate marathon training, especially if you are new to the distance. Some of the myths we address include: The “perfect” training cycle - why it doesn’t exist Why a 20 mile training run isn’t always a necessity before the marathon Marathon training won’t age you - if you do it right! Why training at faster paces isn’t only for advanced runners Injury is NOT an expected part of the marathon training cycle You don’t have to abstain from all alcohol during marathon training Sam's blend of experience, wisdom, and humor make for an episode that runners of all levels can enjoy and benefit from. Whether you're planning your first or 50th marathon, you're bound to discover some valuable training insights!
