Episode notes
Choosing The Race As A Practice Opportunity
- Zach picked Equalizer to practice high-carb fueling and get a race rep before Desert Solstice.
- He treated the event as a learning-focused race with a sub-12 goal as secondary.
Loop Surface Costs Minutes Vs Track
- Zach estimates this 2.09-mile loop is roughly 10–15 minutes slower than a track 100-mile performance.
- Small surface and loop differences matter when margins are minutes at 100 miles.
Early Stops Then Seamless Final 70 Miles
- Zach had two bathroom stops early (mile 11.5 and mile 30) totaling just over three minutes.
- Those were his last stops; the final ~70 miles were uninterrupted running.
