Intro: This is a quick summary of “HUGE Marathon Workout 3 WEEKS Out From BOSTON | Hoka Rocket X2 Review” from Ben Is Running. 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 session is a 34 km marathon‑prep run done 23 days before Boston, built around 7 × 3 km repeats at true marathon pace (≈ 3 min 25 sec / km). This type of session is a fantastic example of how to build race-specific endurance, a core principle we explore in Mastering Interval Training: Science-Backed Workouts and How a Smart App Can Personalize Them.
Each 3 km repeat is followed by a 1 min 30 sec recovery jog, keeping the heart rate low (≈ 125 bpm) and letting the new HOKA Rocket X2 shoe’s responsive p‑Vax midsole shine.
Warm‑up: 5.5 km easy (≈ 4 min 32 sec / km). Cool‑down: 6.5 km easy (≈ 5 min 08 sec / km).
Practical tip: Use a consistent recovery interval to practice pacing under fatigue and to keep the session structured.

Workout Example:

1. Warm‑up 5.5 km @ easy‑moderate pace
2. 7 × {
   • 3 km @ marathon pace (~3:25 / km)
   • 1 min 30 sec easy jog recovery
   }
3. Cool‑down 6.5 km @ easy pace
Total ≈ 34 km

Feel free to adjust the 3 km pace to match your own marathon goal (e.g., 3:45 / km for a 4:15 marathon) and keep the 1:30 recovery.

Closing Note: Give this repeat workout a go and tweak the paces in the Pacing app to fit your training plan. It’s a solid way to lock in marathon‑pace confidence three weeks out.
