This breakdown covers Boston Marathon 2025 Training! Week EP. 1 ft. RheoFit A1 from Vo2maxProductions. Here’s what you need to implement the workout today.
Key Points:
- The session combines steady-state intensity with higher volume, using a steep hill (20% grade) to build strength in the glutes and posterior chain.
- Warm-up consists of 10 minutes at an easy pace on 20% incline.
- The main workout uses a “fartlek” structure: 20 × 90 seconds hard, 90 seconds recovery on a treadmill at 20% grade, maintaining a tempo pace that sits comfortably hard (at or just below lactate threshold).
- This addresses aerobic threshold (LT1–LT2) and develops the hill endurance that comes in handy on courses like Boston’s rolling terrain.
- Practical note: a lactate monitor or effort scale helps you dial in the right intensity for the 90-second work bouts.
Workout Example:
- Warm‑up: 10 min of easy running on treadmill, 20% incline.
- Main Set: 20 rounds of:
- 90 seconds at comfortably hard tempo (roughly 85% max HR, or the effort level just before lactate threshold).
- 90 seconds easy (walk or slow jog) on the same 20% grade.
- Cool‑down: 5–10 min at low intensity, maintaining the incline.
Scale the repeat count or interval duration based on where your fitness sits; this format works for any runner targeting hill strength and threshold durability.
Next Steps: Run this session this week and modify the paces in your Pacing app to match your actual fitness. Your marathon fitness builds one hill at a time.
