How To Run Faster | Training For A 2:09 Marathon

In this video I go through how I improve my speed in marathon training. It's one of the key ways on how to run a faster marathon without actually getting aerobically fitter. You can be more efficient instead! This video is about speed training for runners and how I optimise it in my marathon training schedule as I train for the 2026 London Marathon.
