The CITIUS MAG Podcast | A Running + Track and Field Show

"I missed out on keeping my top ten at a World Major streak when I ran New York. That was my biggest regret: walking away having lost the streak. I want to get back into that rythmn of being in the top ten. I'd love to find myself with 5K or 8K to go feeling like I'm still competing for one of the top spots."

My guest for today’s episode is Susanna Sullivan. She's one of the most consistent marathoners in the United States and someone who’s coming into Boston with good momentum from 2025.

Her last year was anchored by a fourth-place finish in Tokyo, which was a breakthrough on the world stage. She executed, competed, but didn’t fully believe she was in the race for a medal until later on.

Now she heads into Boston with what she describes as her first truly intentional build for this course. She’s focused on hills, especially the downhills, and tailored specifically to the demands of racing Boston. Add in a 1:08 half marathon PR earlier this year, and it’s clear the fitness is there.

In this episode, we talk about that Tokyo breakthrough, the mindset shift that’s followed, what she learned from a demanding 2025 season, and why this Boston build feels different.
