Breakdown of Improve Your Long Runs To Run a FASTER Marathon (Explained) from The FOD Runner. Worth watching in full. We’re pulling out the core ideas so you can get started.

Key points

  • Structure your progression in 3-week blocks: add a few minutes (or miles) each week for two weeks, then scale back the third week and finish with a harder effort segment (about 5 minutes at higher intensity).
  • Extend your longest run progressively: 45 minutes to 60 to 90 to 2+ hours, repeating this pattern.
  • Add intensity at the end. Finishing the last 5-10 minutes harder makes the easy portion feel more comfortable.
  • Use mid-week sessions: fast-finish runs, mile-on-mile-off repeats, and “sandwich” workouts (hard → short jog → harder → jog → hard).
  • Advanced: include specific paces (marathon pace, half-marathon pace, 10K pace) within your long run.

Workout example (adjust paces in the Pacing app)

  1. Beginner progression: two weeks at increasing duration, then a lighter week with a harder finish:
    • Week 1-2: 45 min easy, adding 5 min weekly (50, then 55, then 60 min).
    • Week 3: back to 45 min easy + 5 min hard at the close.
  2. Long run with a hard finish: after 60 minutes easy, add a harder segment:
    • 60 min easy, then 15-30 min at harder effort (no specific pace required).
  3. Mile-on-mile-off (intermediate):
    • 15 min easy, then 1 mi hard / 1 mi easy repeated 3-5 times, then 15-20 min easy to close.
  4. Sandwich workout (intermediate to advanced):
    • 10 min hard, 2 min jog, 5 × 2 min harder efforts, 2 min jog, 10 min hard, easy finish.
  5. Goal-pace long run (marathon block):
    • 30 min easy, 1 hour at marathon pace, 1 hour easy.
    • Or 30 min easy, 30 min at half-marathon pace, 2 min at 10K pace, then repeat.

Closing note Work through these long-run progressions and adjust durations and paces in the Pacing app. Range and marathon fitness build together. Watch the full video for context and motivation.
