In this episode, Addie sits down with Peyton Thomas - a biologist and competitive trail runner whose work explores the connections between aquatic ecosystems, climate change, and community. From growing up in Atlanta and confronting inequities in access to green space, to building a career that bridges research and running, Peyton shares what it means to navigate multiple identities while staying rooted in purpose.

We talk about:

• Peyton’s “aha” moment on climate: canvassing neighborhoods in Atlanta and recognizing environmental inequities.

• Running as a way to process life, find home in new landscapes, and stay connected to the natural world.

• How language learning became a bridge to community in Quebec and her work with the broader Black diaspora.

• The Anticosti Island fastpacking project: sampling rivers, studying brook trout, and blending science with outdoor adventure.

• The balance of pursuing both a science career and competitive running, and the ongoing process of defining fulfillment.
