Most people think, if you run more, you’ll lose fat.  And if you’re training for a marathon, you’ll definitely be running more.

Yet many people don’t lose weight.  In fact, some people actually end up gaining weight when training for a marathon.

Welcome to the Planted Runner. I’m Coach Claire Bartholic and my mission is to help you improve your running, your mindset, and your life with science-backed training and plant-based nutrition.

In today's episode, I’m going to look at some reasons why you might gain weight training for a marathon. 

You’ll learn:

  • why running lots of miles is no guarantee of fat loss
  • why actively trying to lose weight while training for a marathon is bad for both of those goals, and
  • I’ll share my own story of weight loss while training for fast marathons

⭐⭐⭐⭐⭐Love the planted runner

Claire gives great advice on how to make the most out of each run. I look forward to listening to each episode and love the advice on nutrition as well. Claire, one suggestion. Can we hear more interviews from slower runners? (Not those that say I’m slow but still run 8 min miles. I’m talking back of the pack 11-15 min pace.)


⭐⭐⭐⭐⭐Mental Strength!

I found The Planted Runner blog and podcast when I was in the midst of training for my first half marathon this past spring. Coach Claire’s information on a variety of running topics have really helped as a beginner; I especially love the mental strength minute segment! I never thought that running would be a part of my life, but I started a running habit in order to combat postpartum depression. I’m so thankful to have this podcast as a resource so that I can continue to train in an intelligent way, with a lower chance of injury. In the fall, I am planning to run my second half marathon. I am so excited to start my Half Marathon training plan from The Planted Runner in a few weeks. 😁

⭐⭐⭐⭐⭐Run, Grammy, Run

I am so grateful that I found this podcast that provides so many tips and informed support for me as a 62 year old vegan runner who is pursuing a goal to qualify for the Boston Marathon. From the interviews with Des Linden or the another mother runner or the team providing injury/ recovery tips, I as a 62 year old marathoner find many helpful gems. Thank you! I hope to join your PR Team soon.
