This week on the Route 66 Marathon Podcast, we’re joined by first-time marathoner and Route 66 Ambassador Summer Jowers, whose transformation — both in running and lifestyle — is as inspiring as they come.

Summer shares how she shifted from a high-calorie, fast-food lifestyle to a 90% plant-based diet, drastically improving her health, recovery and performance. She opens up about training with Jeff Galloway’s method, the importance of strength work and the role her running community, Girls Who Run DFW, has played in keeping her motivated.

Plus, hear about her supportive husband, her big goals and why Route 66 is the perfect place to run her first marathon.
