42nd Annual Greenfield Triathlon

THE 2026 MARATHON IS FULL. THERE IS NO WAITLIST AND NO BIB TRANSFERS.

The New England Green River Marathon is one of the most beautiful races in New England. Starting in Marlboro, Vermont and following the course of the Green River through an 1870’s covered bridge, and ending with a finish-line celebration in the shade of maple trees at Greenfield Community College in Massachusetts. This USATF-certified (Certification MA18003JK) course has a net 1,400 foot drop over a rolling, downhill course that has seen many personal best and Boston qualifying times for well-trained runners. Choose below from either the regular entry, OR if you want to support the Connecticut River Conservancy by raising an additional $250, join the Stream Team! This funding will go directly to the CRC for their efforts to restore and advocate for clean water, healthy habitats, and resilient communities to support a diverse and thriving watershed.

Connecticut Valley Century Ride – A Scenic & Meaningful Cycling Event!!

• Date: Sunday, September 13, 2026

Explore the Beauty of the Connecticut River Valley

Riders will traverse rolling terrain, passing farmland, waterfalls, and a charming covered bridge over the Green River near Greenfield, Massachusetts. The routes follow the West bank of the river to Brattleboro, Vermont, then cross into New Hampshire before returning along the East bank through picturesque landscapes.

Ride for a Cause

Organized by the Rotary Club of Amherst, this all-volunteer event supports the Amherst Rotary Good Works Fund, which provides local scholarships and funding for charitable programs throughout Hampshire County.

Fundraise for a Cause Through Cycling!

Do you have a favorite local charity you’d love to support? Now you can!

We are a proud host of the Special Olympics Massachusetts Extra Mile Cycling event for Massachusetts. Last year, Kevin’s Krewe 2025 made an incredible impact—31+ riders and 330+ donors raised $46,107.00 for Special Olympics Massachusetts Extra Mile, using the COVAC supported ride platform.

Join the movement—on your own terms!

Fundraising is completely optional—you can participate in the ride just for the joy of cycling or take it a step further by supporting a cause close to your heart. Here’s how:

• Register for the COVAC Ride.

• Ride solo or with a team—you decide how you participate.

• If you choose to fundraise, all donations can go directly to the charity of your choice or to the Rotary Club of Amherst Good Works Fund.

The Rotary Club of Amherst Good Works Fund is a 501(c)(3) non-profit organization, meaning all donations made directly to the Rotary Club of Amherst Good Works Fund are tax-deductible.

Whether you're riding for a cause or simply for the experience, you’ll be part of an unforgettable event. Let’s ride, make memories, and create positive change!

Kilowatt Cross is also a part of the River Valley CX Series where there will be cumulative points across multiple races in western Mass. Other races in the series include: Blunt Park (8/24), Hydra Cross (8/31), West Hill Cyclocross Race (9/20), and Tree House CX (10/19). Categories that are part of the series are denoted in the category notes.

We strive to create an atmosphere that makes all feel welcome. From Pros to first-time racers, from staff to spectators, we will not accept behavior that is deemed to be bullying or any form of harassment and violators will be asked to leave.

At any point, if you feel uncomfortable or unsafe or see behavior that seems to be making someone else uncomfortable, please speak to an official or staff member.

FOOD and BEVERAGES

We are happy to be offering the following during the day of the race:

• Food: El Chapincito Food Truck | MENU | 11 AM - 4 PM

• Beer: The Brewery at North Star Farms Pour Truck | MENU | 11 AM - 4 PM

FIRST TIME RACERS

We at Kilowatt Cross value the importance of 1st time racers. We strive to make them feel welcome and will try to ensure they have a positive first experience with Cyclocross.

There will be an introduction clinic on Saturday, September 26th at 8 AM, open to new and beginner riders. You will ride the course and learn how to navigate the twists, turns, and obstacles. You will also learn basic skills to give you an edge on race day. You can sign up on the registration page.

We recommend bringing a bike with wider, possibly knobbier tires than a road bike. Your mountain bike, gravel bike, fatbike, or even your commuter bike is the perfect tool! Tires that measure more than 35mm are perfect!

We welcome all questions, please message us at [email protected]
