S11E08: Marc Márquez: The Magnificent or the Merciless? Feb 20, 2026

Show notes

Is Marc Márquez the greatest of all time? To kick off the 2026 MotoGP season, Zack and Spurg sit down with legendary racing journalist and historian Mat Oxley to discuss why Márquez is a "generational talent".

They dive into the incredible story of how Marc learned to save front-end slides with his elbows, the countless surgeries it took to keep him on the grid, and how Spain has created the most successful racing culture in the world.

The guys also take a look towards the future at the 2027 MotoGP rule changes that could reset the entire field—and whether Márquez's body will let him stick around to see them.

This entire conversation was inspired by Mat's new book, "Marc the Magnificent: Seven-times MotoGP King". To check out Mat's book for yourself, here is a link to his website.
