Description
Zach Bitter joins Coach Smulders to talk all things running — from his late start in the sport to setting a 100-mile world record. They dive into high-volume training, intrinsic motivation, and his new high-carb fueling experiment (~96g/hr) as he prepares for another record attempt at Desert Solstice.
Highlights:
-How consistent training turned a 15:39 5K runner into a world record holder
-The “pinch point” at mile 62 — where every 100-miler is won or lost
-Why Bitter switched from low-carb to high-carb fueling after 14 years
-The mindset behind enjoying the process, not just the result
