Marathon progression & training volume

A progression built on consistency and gradual increases in volume, with constant attention to injury prevention.

Evolution of training volume and marathon performances of Swiss endurance athlete Frédéric Splendore between 2022 and 2025. This graph highlights the progression of weekly training load and marathon results, illustrating the structured development that led to national-level performances and continuous improvement in long-distance running.

These volumes include approximately 50,000 m of elevation gain in 2025, reflecting a varied training approach combining road and mixed terrain.
All of this was achieved alongside a full-time professional activity.
