I have run this race several times: the full (x2) and the relay (x2). This is a "big" race for Vermont, with a few thousand marathoners, and a 2 person and a 3-5 person relay that runs alongside the full. It occurs over Memorial Day weekend. The course is fair with one big hill around mile 15 and mostly rolling terrain otherwise.

Pros:
-Shamrock-style course is very spectator friendly
-The city of Burlington really comes out to support this race
-Neighborhoods are amazing and set up their own cheer and aid stations
-Sections of the course are very beautiful
-Well-organized staff and volunteers, good swag

Cons:
-The weather is very iffy. I have run it when it was rainy and cold, but more often than not it can be hot/humid. The race was black flagged due to heat in 2016.
-Portions of the course are pretty dull, but the neighborhood spectators make up for it!
-When running the full, I don't love running with the relay because mentally it can be tough having fresh relay runners blow past you, and it can feel congested in narrow portions.

OVERALL: I will continue to come back to this race since I am local. It is a fun race and definitely worth doing, but maybe not a PR race depending on weather.
