This is a quick summary of “Highest Monthly Volume of my ENTIRE Life | Lessons” from Seth James DeMoor. It’s a great watch — we’re breaking it down so you can try the take‑aways today. Be sure to check out the full video for all the details.

Key Points

Five straight weeks of 100+ mile weeks (road marathon focus) pushed his aerobic engine to new levels.
The original 14‑week marathon block felt too short; he now plans 16‑week blocks to add a slower‑build start and a proper down‑week.
A down‑week (lower mileage) about 6‑7 weeks before race day helps reset fatigue and prevents stress‑reaction injuries.
Listening to the body and treating each run as a “deposit” into an aerobic bank account is crucial for long‑term health.
Calculated risk‑taking works when you have a solid high‑volume background, but always monitor for pain (e.g., his past metatarsal stress fracture).

Workout Example (Typical 100‑Mile Week)

Mon – Easy 6–8 mi @ conversational pace
Tue – Medium 10–12 mi @ steady (half‑marathon effort)
Wed – Hard quality: 8 mi with 2×1 mi @ 10K pace
Thu – Recovery 5 mi easy
Fri – Easy 6 mi + strides
Sat – Long run 20–22 mi @ easy‑moderate
Sun – Back‑to‑back long 18–20 mi @ easy
Total ≈ 100 mi

Adjust distances and paces to match your own weekly mileage and current fitness level using the Pacing app.

Practical Tips to Try Now

If you’re planning a marathon, aim for a 16‑week block instead of 14; use the first week to add mileage gradually.
Schedule a down‑week (≈ 70 % of peak mileage) about 6–7 weeks out from race day.
Treat each run as a small “deposit” toward your aerobic bank—track them in a training log or app.
Pay attention to early signs of fatigue (e.g., “legs barking”) and back‑off before injury.

Closing Note Give these volume‑management strategies a shot in your next training cycle and tweak the paces to suit your own limits in the Pacing app. You’ll be building a stronger aerobic base while staying injury‑free. Happy running!
