Running coach Rafa Aguilar explains how he quit vaping, went from throwing up after his first 5K to running a 2:45 Houston Marathon, and earned a Boston Marathon qualifying time in less than three years.
Rafa shares the marathon training, strength work, fueling plan, running community and negative-split pacing strategy behind his transformation—including how he saved his hardest effort for the final 10K and closed Houston with sub-six-minute miles.
