Intro: This is a quick summary of Marathon Training Week 13: Mileage, Workouts, Mental Strategy 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 13 is a taper: cut weekly mileage from ~120 mi to 65‑70 mi (≈105‑113 km) to let legs recover.
Target mileage two weeks out: 35‑40 mi (≈56‑64 km) before race day (April 19).
Mental tip: embrace the taper, stay vigilant of negative thoughts, and view the lower volume as “freshening up” the legs.
Easy run example: 3 mi (≈5 km) at ~9 min/mi (≈5:35 min/km) on the Ultra Provision shoes.
Final speed session: 8 × 600 m intervals on the track, keeping effort sharp before the marathon.

Workout example:

Easy run: 3 mi (5 km) easy, ~9 min/mi pace.
Taper mileage: Run 65‑70 mi (105‑113 km) total this week, splitting into easy runs and a long run ≤20 mi (32 km).
Final interval session (week before race): 8 × 600 m on the track, jog recovery 90‑120 s, aim for ~5‑10 s faster than your 5 k race pace.

Closing note: Give the taper a try, adjust the paces to fit your own training, and log the session in the Pacing app so you can fine‑tune it for race day. Happy running!
