Here are the top times that I could find for the Lowell Invitational since 2006 (current course). If you know of other times that break into the following lists, please post in the comment section below. The course length for 2018 may have been slightly different since the runners did not go around the big tree. This is also a very unofficial list since the course has fluctuated through the years.
