Key Points for Long Runs

  • Pick a mileage that suits your current training status
  • Run these runs at an easy pace
  • Build mileage slowly, 1-2 miles/week initially, then as runs get over 10-12 miles, a 2 mile jump every other week is appropriate.
  • Add in walking breaks as needed
  • Practice hydrating and snacking as mileage increases (runs over 90 minutes)
  • These runs are performed on the most difficult section of the marathon course
  • Note: some of the more advanced plans long runs may exceed scheduled mileage
