The Barn to Run Trail Race Series is produced by Sun Multisport Events (SME). The first race in the series was the Powisset Farm Trail Run at Powisset Farm (Dover, MA) in 2015.  As the event grew so did interest in additional farm-based trail races and in 2017 the Weir River Farm Trail Race (Hingham, MA) was established and then a trail race at Chestnut Hill Farm (Southborough, MA) in April 2018. The events were brought together under the Barn to Run Trail Race Series name for the fall of 2018 with a goal to expand to more farms in 2019 (drop us an email if you have a venue in mind at
