The 10K course was last certified in 2016 by Courtney Bird of USA T&F New England. The 5K course was altered in 2018 and is no longer a certified course – and as of 2022, there is no longer an associated 5K. With the exception of a modified course in 1997 due to construction at Chatham High School, the 10K course has been largely unchanged for the past 40 years. The 10K course certification is MA16018JK. The certified course map for the 10K course is provided below for your reference.
