Running 140 Miles per Week - Seth James DeMoor

Aug 13, 2025

Intro: This is a quick summary of Running 140 Miles per Week from Seth James DeMoor. 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:

Functional overreaching: Seth has been “functionally overreaching” for the past two weeks, deliberately pushing volume while keeping intensity manageable.
140 mi weekly volume: He aims to keep the total mileage steady at 140 mi, with the vertical gain dropping from ~20,000 ft to about 9‑10,000 ft in the coming weeks.
Recovery/Easy day: One easy‑recovery run each week (4–5 mi) keeps the body fresh and helps knock the total over 50 mi before a rest day.
Mountain focus: Lots of elevation work (mountain runs) is used to build strength and mental toughness.
Tracking & tools: He logs everything on Strava, uses multiple shoes for different paces, and emphasizes foam‑rolling, sleep, and nutrition as part of the plan.

Workout Example:

Weekly 140‑mi plan (example)
- Mon: 12 mi easy (gel cayenne light 2) – flat run
- Tue: 15 mi mountain + 2,000 ft gain (endurant shoe)
- Wed: 10 mi recovery (gel cayenne light) – 4‑5 mi easy
- Thu: 18 mi mixed tempo (endurant shoe) – include 3–4 mi at 10‑sec faster pace
- Fri: 12 mi easy + 1,500 ft gain
- Sat: 25 mi long mountain run – aim for 5,000 ft gain
- Sun: 4‑5 mi recovery (easy) – knock weekly total >50 mi before rest
Total ≈ 140 mi, vertical gain ~9–10k ft.

Practical Tips:

Track every run on Strava to monitor volume and elevation.
Schedule one short easy run (4‑5 mi) each week to stay under 50 mi before the rest day.
Rotate shoes: light‑weight for easy days, cushier for mountain work.
Prioritize recovery: foam‑roll, get extra sleep, and eat a bit healthier on high‑volume weeks.
Listen to your body: functional overreaching means you’re a bit fatigued but still able to complete key sessions.

Closing Note: Try this high‑volume, mountain‑focused routine (or adapt the mileage/pace to suit your own training) and watch how your endurance and strength grow. Log the session in the Pacing app, tweak the paces to fit you, and keep an eye on your weekly totals. Happy running!
