Intro

This is a quick summary of Marathon Training Monday Week 10: Good or Bad? 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

Week 10 of an 18‑week marathon plan (9 weeks completed) focuses on low‑heart‑rate easy runs, steady‑state/tempo work, and a long run at a comfortable “feel” pace.
Seth emphasizes training by feel – his legs felt good at about 9:23 min/mile for the long run, which he considers a positive sign compared to earlier, more fatigued blocks.
The week includes strength work in the gym to build resilience before the final taper.
He’s not doing heavy speed work yet; the focus is on slow mileage, threshold work, and strength.

Workout Example

Long Run (Feel‑Good Pace): 10‑12 mi at a comfortable 9:20‑9:30 min/mile (or adjust to your own “easy” pace). Keep heart rate low, stay relaxed, and focus on how your legs feel.
Strength Session (after run): 20‑30 min of body‑weight strength (e.g., lunges, single‑leg deadlifts, core work) to build leg stability.

Closing Note Feel good, stay consistent, and tweak the paces to match your own fitness level in the Pacing app. Give this feel‑good long run a try and keep building strength – you’ll be ready for Rotterdam!
