How to Use Interval Training to Prepare for a Hilly Marathon Course
Do weekly hill intervals on a 6–8% grade to build quads, hamstrings, and glutes with less joint stress than flat speed work, using 400m+ climbs to mimic marathon terrain like Boston’s Newton Hills, sprinting up with short, powerful strides and a forward lean from the ankles, then jogging down with midfoot strikes to boost eccentric control, all while replacing one weekly aerobic session-see how top runners structure these sessions for sustained race-day strength.

Notable Insights
- Perform weekly hill intervals to build strength and cardiovascular endurance specific to hilly marathon demands.
- Choose hills with 6% to 16% gradients to effectively simulate race conditions and improve climbing efficiency.
- Use short, powerful strides and lean from the ankles to maintain proper form during uphill efforts.
- Land on your midfoot and avoid overstriding downhill to reduce muscle damage and improve control.
- Complete 12–20 minutes of total uphill running per session, with jog-down recoveries to enhance rhythm and recovery.
Use Hill Intervals to Build Marathon-Specific Strength
While you’re prepping for a hilly marathon, adding hill intervals to your weekly routine is one of the smartest moves you can make to build race-specific strength. Running hill repeats on a 6% to 16% grade-like those on Summit Ave in Brookline-helps build strength in your quads, hamstrings, and glutes, essential for tackling sustained climbs. Doing 6 x 3-minute or 8 x 2-minute uphill efforts at increasing intensity gives you 12–20 minutes of marathon-specific strength work with less joint impact than flat intervals. Short, powerful strides and a forward lean from the ankles improve neuromuscular recruitment, prepping you for brutal ascents like Heartbreak Hill at the Boston Marathon. Easy downhill jogs recover actively while boosting eccentric control, reducing injury risk. One weekly session of hill workouts safely increases cardiovascular load and leg strength during high-mileage phases, making it a cornerstone of smart marathon training.
Choose Hills by Gradient and Length for Your Goals
Pick hills that match your training goals, and you’ll get way more out of each interval session. For building leg strength and power, choose a gradient between 6% and 16%-this range challenges your cardiovascular workout without compromising form. If your marathon training plan includes sustained climbs like the Boston course, opt for moderate 5–8% grades and longer hills (400m+) to mimic race-day running uphill during long runs. Need explosive power? Go for short, steep hills (50–100m at 8%+) to nail hill sprints that boost neuromuscular drive. Aim for a length that supports 2- to 3-minute efforts, aligning with common hill training formats like 6 x 3 minutes. Make sure the surface is paved or packed for safe, repeated recovery jogs. The right hill length and gradient fine-tune your strength and endurance efficiently.
Run Uphill and Downhill With Proper Form
When tackling steep climbs during interval training, leaning forward from the ankles-not the waist-keeps your body aligned and helps you drive powerfully up the hill without wasting energy. Use powerful strides and lift your knees higher to engage glutes, quads, and calves, especially on gradients like those in Newton Hills. For downhill running, maintain excellent running form by landing on your midfoot or forefoot to reduce strain on muscle fibers and avoid overstriding. Keep your head up, eyes on the horizon, and relax your shoulders-this is key on long hilly courses. A good running coach always emphasizes control and rhythm.
| Phase | Focus | Benefit |
|---|---|---|
| Uphill | Lean, short strides | Engages power, saves energy |
| Downhill | Midfoot strike | Reduces muscle damage |
| Both | Relaxed form | Boosts endurance, prevents injury |
Add Hill Intervals to Your Weekly Training
You’ve got your uphill and downhill form dialed in, so now it’s time to put that technique to work by building hill intervals into your weekly routine. Aim to incorporate hill sessions once a week, replacing a regular speed or aerobic workout. Find a hill with a 6% to 16% grade, long enough for 2-minute repeats-like Summit Ave in Brookline. Warm up with 1.5–3 miles easy, then log 12–20 minutes of total uphill running, using a type of session like 8 x 2 minutes. Start at marathon pace, build to much faster efforts, and rely on perceived exertion, not data. This works different muscles than flat runs, is great for building strength and power, and doubles as low-impact strength training. Recover by jogging downhill. You’ll hit maximum effort by the final repeat, boosting endurance and resilience with less joint stress.
On a final note
You’ve built strength and stamina by tackling hill intervals at 4–8% gradients, using proper form uphill-short strides, forward lean-and control downhill. Keep weekly sessions consistent, wearing responsive shoes like the Saucony Endorphin Speed 3 for cushion and turnover. Pair with carb-loading three days pre-race and hydrating with 16–20 oz water hourly during long runs. This targeted work, tested by runners prepping for hilly courses like the San Francisco Marathon, cuts injury risk and boosts finishing confidence.
