In this special Road to the Trials episode, Peter Bromka and Matt Chittim team up with Brendan Gregg, the Course Director of the California International Marathon and a former CIM champion, for the ultimate 2025 race preview.

Brendan brings insider knowledge from both sides of the barriers: years of experience designing and refining the course, and firsthand insight as an elite athlete who has mastered it himself. Together, the trio walks listeners through every key detail of race weekend — from boarding the buses on race morning to navigating the final miles into Sacramento.

Over the episode, Peter, Matt, and Brendan break down:

• What runners should expect at the start, including timing, logistics, and what actually matters in those early minutes before the gun

• How to approach pacing over CIM’s rolling terrain, where to stay patient, and where to open up

• Strategy differences for first-timers, OTQ chasers, negative-splitters, and anyone trying to survive that long descent into the city

• Course features that matter more than people think — and the ones that don’t

• How to stay composed in the final 10K and set up a strong, efficient finish on the streets of Sacramento

Peter also shares lessons from racing CIM five times, giving runners an honest sense of the effort, rhythm, and mental checkpoints that define the race.

Whether you’re racing for a PR, an OTQ, or the joy of a fast December marathon, this is the comprehensive course breakdown you’ll want in your pocket.
