Confirmed from McCarthy Park and Fields' own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.

What runners say about McCarthy Park and Fields

Pulled from public reviews of this trail (28 of them) — the things people bring up again and again, in their own words. Nothing here is written by us.

Trails are well maintained, nice spot to enjoy walking/running through (for pleasure or exercising) also a fantastic spot to go sledding when it snows. One of the only spots in Medfield that hasn’t changed much over the years, hope it’s never developed.

★★★★☆ — Kathleen , Jan 2019

this is a beautiful Medfield Park with a lot of wild area IE not manicured. There is a great sledding hill with parking area at the top of the hill. Now the fields are well-manicured and authorized for use through the town Rec Dept.

Trail conditions & character

What this trail is actually like underfoot and overhead, taken from its own listing and from reviews. Each one links to every other trail with the same character. Busy or quiet is reported as a plain fact, not a plus or a minus — a runner heading out alone at dawn often wants company on the path, and someone running intervals wants an empty one.
