4.25 CHP Mach Z™ Commercial Plus Motor

Choose the motor that will run with you from Chicago to Cape Town. Smooth. Powerful. Durable. Proven. This large-frame Commercial Pro motor stays cool through the toughest workouts; creates high levels of inertia for a smooth, powerful feel; and promises a quiet in-home experience. Great for heavy use, this motor is built with high-grade components proven with our lifetime motor warranty.

20° Incline, -6° Decline

We consider incline training the treadmill game changer—you can literally prepare your body for any hill, any valley. Incline training adds resistance to your everyday workout, burns more calories, and increases muscle tone. The Boston 4.0 offers powered, automatic incline and decline adjustability. For the complete real-world experience, take your grade into the negative for the full range of training.

Runners Flex™ Impact Control

Power on our Runners Flex™ Impact Control and the full-length suspension increases cushioning to reduce impact on your joints. Leave it switched off for road-like simulation. Train for comfort or train for the road—it's totally up to you.

20" x 62" Tread Belt

Because your in-home workout experience should be a comfortable one, ProForm designed a roomy deck so you won't feel confined as you run. The 62-inch length gives your legs plenty of room to stretch out your stride. And the 20-inch width allows your upper-body extra elbowroom. To ensure our treadmills are top quality, we test each belt for one million cycles at double the user weight before release.

10" Full-Color Touchscreen

Training for a major event takes time—and many, many miles. Our built-in full-color touchscreen display connects you to what you need most. It's easy to check on your training stats as you go. Swipe through your speed, time, distance, calories burned, heart rate, and incline/decline stats.

Minimalist/Streamlined Design

At ProForm, we embraced flexibility and independence when designing the Official Boston Marathon® 4.0 Treadmill. Our unique wide-open running platform allows experienced runners to focus on fine tuning their workout without the constricting motor hood and arms of traditional treadmills.

Onboard Marathon Training

We wanted to create a treadmill that would help more runners qualify for the notorious Boston Marathon. So we met up with the Boston Athletic Association coaching staff to create the perfect treadmill to get you there. Choose from 16-week or 20-week programs; then select beginner, intermediate, or advanced level training. We'll get you from Day 1 to Race Day—confidently.

Powered by Google Maps

Tapping into Google Maps™, this exclusive ProForm® treadmill automatically simulates every hill and dip with inclines up to 20 percent and declines of 6 percent. Track your real-time progress using Google Maps™ Street View on our 10-inch full-color touch screen display. And when you connect to your home's wireless network, you can access email, watch sports highlights, get on Facebook®, and more.

Wireless Chest Strap Included

The Official Boston Marathon® Treadmill comes with Lifetime Frame & Motor, 6-Year Parts & Electronics, and a 3-Year Labor Warranty.

Cadence Coach

When you're ready to boost your running efficiency, meet your Cadence Coach. Like a metranome, this audible tone keeps you in sync with your target rhythm so you can reach the finish line—without feeling completely worn out tomorrow.

Dual 8" CoolAire™ Workout Fans

Our dual 8-inch built-in CoolAire™ fans keep your workout comfortable from the moment you step onto the deck to the moment you step off. Choose from two speed settings for instant control—because one of the joys of indoor workouts is climate control.

iPod® Compatible Audio*

Once you create your perfectly paced workout playlist, just plug your iPod® or MP3 player into our built-in sound system. Built with two 3-inch speakers, you can turn up the tunes and turn up the tempo. Experts have learned that we actually increase or decrease our pace to match the tempo of our tunes. Music has also been proven to lower perceived exertion. That's great news.

*iPod® is a trademark of Apple, Inc., registered in the U.S. and other countries. iPod® not included.

2.5" Balanced Rollers

We know that a quality product is all about the details. That's why we've built the Boston 4.0 with 2.5-inch precision-machined, balanced, non-flex rollers. Large belt rollers decrease tension, which keeps wear and tear to a minimum. You'll also notice less noise and better grip.

400 Lb. Weight Capacity

Built with the whole family in mind, the Boston 4.0 treadmill accommodates up to 400 pounds per user.
