3:27 to 2:23 at the Boston Marathon

David Slear shares the training, mileage, and racing decisions behind his 64-minute transformation.

David traces his journey from Princeton lightweight rowing through triathlon and into competitive marathon running. We discuss the fueling mistake that destroyed his first Dallas Marathon, how the DFW running community gave him confidence to chase faster times, and what changed when he began running more than 100 miles per week.

David also explains why he uses two-a-day runs, how he balances training with work and family, and why he races by effort instead of locking onto a specific pace. Whether you’re chasing a Boston qualifier, building marathon mileage, or trying to break through a plateau, this conversation offers an honest look at what major improvement requires.
