Intro: This is a quick summary of Hardest Training Block Phase for Runners Starts Now 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

The hardest block was a 130‑mile week with ~22,000 ft of vertical gain on Pikes Peak, often done with a weighted vest.
After such a high‑stress period, the body needs the biggest taper – lots of rest, extra sleep (12‑13 h per night), and a sharp cut in volume and elevation.
Early‑morning runs (2 am‑4 am) can disrupt sleep; aim for a consistent schedule to let the legs fully recover.
During taper, keep runs easy, flat, and short (≤5 mi) while still doing light gym work for leg strength.
Practical tip: track sleep and recovery; if you’re not getting the extra rest, the taper will be ineffective.

Workout Example (Adaptable to Your Paces)

Hard‑Block Reference (for context only): 15 mi mountain run @ moderate effort, 2,500 ft elevation, wearing a 10‑lb vest – total week 130 mi, 22k ft gain.
Taper Week (7 days):
- Day 1: 4 mi easy on flat terrain @ 1 min per mile slower than your normal easy pace.
- Day 2: Rest or 20‑min gentle yoga/stretch.
- Day 3: 3 mi easy + 20 min strength (single‑leg dead‑lift, calf raises).
- Day 4: Rest – aim for 12 h of sleep.
- Day 5: 5 mi very easy, no hills, focus on relaxed breathing.
- Day 6: Light gym – 30 min low‑impact cardio + core work.
- Day 7: Full rest, prioritize 13 h of sleep. (All distances are in miles; adjust paces to match your current fitness level using the Pacing app.)
