The Western Greenway 5K

Since 2013, the Waltham Land Trust has held the Western Greenway 5K walk and run benefit event where people of all ages traverse a 5K distance through the Western Greenway. We missed you all in 2020 but are excited to be offering the race again in 2021!

The 5K (3.1 mile) course goes through and around a variety of habitats in Beaver Brook North Reservation and Rock Meadow, including cattail marshes, forests, vernal pools, and open meadows. Please note, there is a change to this year's race route from the last race in order to eliminate the trail over a small bridge where runners expressed concerns that it was often slippery under the conditions that typically are present during the race.

The 2021 Western Greenway 5k is scheduled for Sunday, October 31, 2021 at 1:00pm. We're happy to report that as of August 24, 2021 the City has given WLT the go ahead to hold the race in person.


Online registration closes at 10pm on Thursday, October 28, 2021. There is an additional $5 fee to register at bib pickup, or the morning of the race. While we hope that nothing changes between now and October, we will need to respect whatever public health guidance is in place at that time. Because WLT relies on the proceeds from the race to fund its work and we expend certain costs, race registrations are not refundable.
