Course, aid, awards and logistics
The race uses a two-loop, oceanside course along Narragansett Bay and Bristol Harbor.

There is a 3.5 hour course cutoff.
There are three aid station locations that are visited twice (six stops total). At roughly mile 1.5 and 7.75 the Stone Bridge aid station provides water only.
