Intro: This is a quick summary of Boston Marathon 2025 Training! Week EP. 1 ft. RheoFit A1 from Vo2maxProductions. 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 emphasizes moderate‑quality, higher‑volume threshold training using a steep hill (20 % grade) to activate glutes and posterior‑chain strength.
Warm‑up includes 10 minutes of easy running at 20 % incline.
Main set is a “fartlek” style interval: 20 × 90 seconds on, 90 seconds off on a treadmill set at 20 % grade, running at a tempo pace that feels comfortably hard (near lactate threshold).
The workout targets aerobic threshold (LT1‑LT2) and builds hill‑repeat endurance useful for hilly marathon courses like Boston.
Practical tip: keep a lactate or effort meter handy to gauge the “moderate tempo” effort during the 90‑second work periods.

Workout Example:

Warm‑up: 10 min light jog on treadmill, 20 % incline.
Intervals: 20 rounds of:
- 90 seconds running at a comfortably hard tempo (≈ 85 % of max HR or “just below lactate threshold”).
- 90 seconds easy recovery (walk or slow jog) on the same 20 % grade.
Cool‑down: 5‑10 min easy run at low effort, still on the incline. Adjust the number of repeats or interval length to match your current fitness; the structure works for any runner looking to boost hill strength and threshold stamina.

Closing Note: Give this hill‑interval session a try this week and feel free to tailor the paces in your Pacing app to suit your own fitness level. Keep pushing forward—your next Boston marathon breakthrough is just a hill repeat away!
