Changing Landscape of Marathon Running

The landscape of marathon running has drastically changed over the years, shifting to a more speed-based race where the focus is on running one's best rather than just finishing. Training for marathons now emphasizes speed work alongside threshold runs. Despite these changes, staple workouts like 10 by 1000m with rest remain crucial as they contribute to improving the body's ability to handle and buffer lactic acid, a key factor in marathon performance.
