Intro: This is a quick summary of Can You Run a Faster Marathon? Here’s How to Know from Lee Grantham. It’s a great watch — we’re breaking it down so you can try the workout today. Be sure to check out the full video for all the details.

Key Points:

Your half‑marathon time is a useful benchmark for estimating marathon pace. Similarly, your performance in shorter races can provide crucial data; knowing how to approach a faster 10K, for instance, can help you set realistic yet ambitious marathon training paces. A sub‑3 hr marathon is realistic with the right training built on these benchmarks.
Focus on “key sessions” that push you just beyond your current comfort zone. While this article highlights progressive pace runs, another cornerstone for building speed and efficiency is interval work. For a comprehensive look at how to structure these workouts, our guide on Mastering Interval Training: Science-Backed Workouts and How a Smart App Can Personalize Them is a great resource. Even sharpening your short-distance speed has a huge carryover, so don’t be afraid to incorporate workouts from our guide to Mastering 5K Speed: Proven Interval Strategies to Cut Minutes off Your Time.
Consistency, belief, and redefining “failure” as a learning step are essential mental tools for the long journey of marathon training.

Workout Example (Progression Run):

Warm‑up 1–2 km easy.
Run 8 km at 7:48 min per mile.
Run next 8 km at 7:24 min per mile.
Finish with 8 km at 6:45 min per mile. Total: 24 km with a clear negative‑split pattern that simulates faster marathon effort.

Closing Note: Try this progression run this week, adjust the paces to match your current fitness, and track the results in the Pacing app. You’ll be one step closer to that sub‑3 hr marathon—keep believing, stay consistent, and enjoy the freedom of faster running
