Intro: Below is a condensed version of Lee Grantham’s 5 Essential Long Runs for Crushing Your 3:30 Marathon Goal. It’s an excellent resource, and we’re pulling out the essentials so you can get one of these runs into your training schedule this week. The full video has more commentary and context if you want the complete picture.

Key Points:

  • Each long run targets something specific: building aerobic capacity, practicing marathon pace, developing strength, or tackling hills.
  • Your goal marathon pace is 5 min/km (8 min/mi).
  • Add roughly 10 % to your weekly volume each week, starting from your current longest run.
  • Keep aerobic runs in Zone 2 (conversational pace) and stay out of Zone 3.
  • Use elevation changes and pace variation to build leg strength and race confidence.

Workout Example (pick one to fit your week):

  1. Classic Long Slow Distance with a Twist – Head out for 10 mi (16 km) over rolling ground at an easy Zone 2 pace. Begin with a 1‑hour base run and build your weekly volume by roughly 10 %.
  2. Marathon‑Paced Run – 15 km total: start with 5 km easy (Zone 2), move into 5 km at 5 min/km (marathon pace), finish with 5 km easy. As your fitness grows, extend that middle marathon‑pace section.
  3. Progressive 8‑8‑8 Run – 8 km easy, 8 km at marathon pace, 8 km easy (or dial back the middle segment to 10 % slower if you need a step back).
  4. 2 km Pace Alternation (20 km total) – Cycle between 2 km at marathon pace (5 min/km) and 2 km at either 10 % faster (roughly 4:30 min/km) or 10 % slower (roughly 5:30 min/km).
  5. Hill Long Run – Start with 10 km at marathon pace (or dial it back 10 % if needed), climb 5 km at a 6‑7 % grade, descend for 5 km, and close with 10 km at marathon pace.

Practical Tips:

  • Focus on how your body feels, not the numbers on your watch—disable the display or just watch heart rate.
  • The first easy portion of a marathon‑paced run doubles as your warm‑up; you’re preparing your system as you go.
  • Add distance or time gradually from week to week; make sure your mileage growth stays under 10 % to prevent overuse injuries.
  • Hit hills hard to develop your glutes, hamstrings, and quads, then work the same intensity on descents to train for a strong finishing kick.

Closing Note: Pick one of these workouts and run it this week—adjust the paces based on your data from the Pacing app. You’re going to feel the difference in strength and speed, and you’ll have what you need for that sub‑3:30 marathon. Get out there. (And catch the full video if you want more detail.)
