Intro: a summary of “All Roads Lead To LONDON MARATHON - Week 10” by The FOD Runner. Here’s what you need to run the workouts. Watch the original for context.

Key points:

  • Monday: 16-mile marathon-pace effort at around 5:56/mi. The week’s hardest session at goal pace.
  • Tuesday: low-intensity recovery run, HR in the 120s.
  • Wednesday (double day): three threshold blocks of 10 minutes at around 5:45-5:44/mi, with 2-minute jog recoveries.
  • Friday: easy run, relaxed effort throughout.
  • Saturday: 2 h 30 min long run, around 18.6 miles. Start easy, settle into 6:30-6:45/mi.
  • Nutrition: don’t skimp on post-run fuel, especially after long runs. Carbs and whole foods set you up for the next hard session.
