I started listening to podcasts to make it easier to run on the treadmill, one of my most hated things, yet something necessary if I am going to stay in shape on the road. These days, I listen to them while flying, while driving, and sometimes even while getting ready in the morning.

Here are some of my favorites. Please share yours!

The Knowledge Project by Shane Parrish.

This is the first ever podcast I listened to. The Angel Philosopher episode with Naval Ravikant is still one of my favorites ever, I have now listened to it twice.

Living It by Kelly DiNardo and Amy Pearce-Hayden.

This is a new podcast, started by my friend Kelly, a project that came out of her book Living the Sutras. I love the theme of “living life on purpose” and particularly enjoyed this week’s episode with Michelle Gielan.

How I Built This with Guy Raz by NPR.

These are interviews of entrepreneurs and how they built their business. I got turned on to this podcast because of an episode featuring Marcia Kilgore and her story about Bliss – and have been addicted ever since. The episode with the two founders of SoulCycle is also amazing.

Freakonomics Radio by Stephen Dubner.

This podcast definitely takes me out of my comfort zone and introduces me to topics I don’t typically think about. One of my favorite episodes is How to Catch World Cup Fever, from this past summer.

And here are some podcasts I downloaded but have yet to listen to…

Best of Both Worlds by Laura Vanderkam and Sarah Hart-Unger. I got turned on to this one after reading Laura’s book Off the Clock, which I loved.

The Business of Fashion. This is one of my favorite daily newsletters (I wrote about these here). I just need more hours in the day.

What are your favorite podcasts? And when do you listen to them?
