The ProForm Boston Marathon 4.0 has a web price of $2999 (full price $3999) and is backed by ProForm’s longest warranties for parts and labor.

Workout Programs

Boston Marathon Treadmills have built-in training programs and can also be used with iFit’s wireless programming.
The built-in programs are especially for marathon training. You can choose from a 16-week or 20-week prep course and three skill levels (beginner, intermediate and advanced). Each training course features high definition video filmed along the Boston Marathon route.

The Boston Marathon 4.0 Treadmill is iFit-enabled; a special iFit monitor isn’t required. You can access iFit’s unlimited workouts by using the integrated 10″ touch screen or your own mobile device, which can be securely docked on the console. iFit lets you simulate any running route with help from Google Maps™; you’ll get a Google Street View as the track is automatically tilted up and down to replicate the landscape. Some other iFit benefits: Download new personalized workouts every day, choose from hundreds of HD video workouts, compete in online races and use advanced automated stats tracking.

Boston Marathon 4.0 Features

The Boston Marathon 4.0 is the only ProForm treadmill offering wireless speed control. Wearing a SpeedRing™ on your finger, you can adjust the track speed without breaking your stride.

Another top feature on the Boston 4.0 is its power incline/decline. With a range of -6% to 20%, the ramp helps to simulate actual terrain while giving you an extra training boost.

Adjustable cushioning is another feature that many outdoor runners appreciate. You can leave the cushioning activated to reduce the physical impact of running, but you can turn it off for a better approximation of running on the road.

To help maximize your efficiency this marathon treadmill arrives with a wireless chest strap and also has Cadence Coach technology. The Cadence Coach is a metronome with audio to help you maintain a consistent pace.

For entertainment the console has a sound system (a smartphone-compatible port and 3-inch speakers).

The same 10″ full color touch screen that’s used for the HD video marathon workouts can be used for surfing the web.

Two 8-inch CoolAire™ workout fans are integrated with the console too.
