The third running of the Cape Cod Move ‘Y-Not’ Trail Races have been canceled due to the COVID-19 pandemic.

The event had been scheduled for Saturday, Sept. 26, and included a 50K ultramarathon, marathon relay, marathon, half marathon, 10K, 5K, kids’ fun run, and race expo. Following a successful first year in 2018 that offered all of the sub-ultra distances, the 50K was added in 2019. Fourteen runners completed the 50K that year, including a blistering performance by Cambridge resident Padraig Mullins who established the men’s course record of 4:12:34. Vermont resident Elizah Markwood took home the inaugural women’s victory in 5:47:56, holding off West Newbury’s Tara Driscoll by about 10 minutes.

The ‘Y-Not’ 50K is the 11th Massachusetts ultramarathon to be canceled due to the pandemic this year. Several other races have either been postponed or opted for virtual formats instead.

As of today, the next in-person ultramarathons on the calendar in Massachusetts are the East End 50K on August 2 at Borderland State Park in Easton and the TARC Summer Classic on August 8 at Noon Hill Reservation in Medfield, though the race directors of both events continue to monitor the situation.
