How Jéssica Fazzio Ran a 3:14 Marathon in Barcelona
Free from race pressure, the runner built an aerobic base on the treadmill, earned a Boston qualifier in Barcelona, and set new PRs in the 10K and half marathon.
Jéssica Fazzio shared on Girls Who Run how pandemic isolation and higher treadmill mileage transformed her performance. That consistency culminated in a 3:14 finish at the Barcelona Marathon and personal records in the 10K and half marathon.
The transition from an everyday amateur runner to hitting competitive paces rarely happens overnight. For Jéssica Fazzio, the journey was built mile by mile: after starting out with paces around 7:00/km and 6:00/km, locking in her first workouts at a 4:00/km pace felt like a reality reserved for professional athletes. After debuting in the marathon with a 3:48 and earning another lottery entry for Chicago, the onset of the COVID-19 pandemic in March 2020 forced an unexpected pause on the racing calendar.
Building a Silent Aerobic Base on the Treadmill
With lockdown restrictions and the cancellation of in-person races, Jéssica bought a treadmill to train at home. Under the guidance of her coach, Nelson, her training focused almost entirely on steady, easy mileage. Free from the fatigue and pressure of an intense race-specific block, her weekly volume climbed steadily into the 60 km to 70 km range, building an aerobic foundation that would fuel major breakthroughs in the years ahead.
Returning to the Parks and Unlocking Faster Paces
When public spaces began reopening in 2021, the benefits of more than a year and a half of base building surfaced during speed sessions. Interval workouts in the park easily dipped below a 4:00/km pace, and 16 km steady runs at Parque Bruno Covas held strong at a 4:30/km pace. Jéssica's initial goal—securing a Boston Marathon qualifying time with a 3:25—began to look conservative relative to her true fitness level.
2021 Barcelona Marathon: Consistency and a 3:14 Finish
With US borders still closed and Chicago out of reach in 2021, the alternative was entering the Barcelona Marathon, one of the first major international races to reopen to foreign runners. Her training target suggested a finish between 3:10 and 3:15. Jéssica decided to start with the 3:15 pace group to avoid bonking early, maintaining an even cadence from start to finish to cross the line in 3:14.
Breaking PRs in the 10K and Half Marathon
That breakthrough inspired ambitious new goals for the first half of 2022: running a sub-40-minute 10K and a sub-1:30 half marathon. In February, racing the challenging São Paulo Half Marathon purely by feel, Jéssica crossed the line in 1:29, followed later by breaking the 40-minute barrier in the 10K.
Running as a Foundation for Identity
Beyond the numbers on the clock, this running progression reflected a profound journey of autonomy and self-identity. In a corporate career, hard work does not always translate directly or immediately into success; in running, the relationship between training discipline and results at the finish line is clear and direct. This sense of agency and achievement turned running into a cornerstone of self-confidence for facing life's broader challenges.
