The mats were turned off at exactly 3 hrs, even though the past race results showed, 3:19, 3:31, etc, so several runners were very surprised at the Race Director who stated he decided to “Not be as nice this year” WoW!
Mats were still in place thru 3:15, w finisher pics taken & medals awarded, but SURPRISE, no official time. Runners just expect race directors to be consistent w past posted official times. Also, runners required to run with traffic, instead of against traffic, with no
cones.

Well organized, small scale half marathon Manchester-by-the-Sea; however the route is not really near the ocean. The course is mostly flat with some mild rolling hills, but not much to worry about. There are two sections over gravel/dirt road that are tricky – watch your ankles!
The roads are open during the race, but traffic is mostly minimal and respectful.
The race is well organized by Yukan (as in “Yu Kan Run”) with some good swag for the cost of the race (medals, tech shirt, running cap) and decent food/drink options afterwards (water, energy bars, bananas, the best cider donuts ever, chocolate chip cookies and NA beer).
Overall a fund, low key half and a very easy course – good for a PR before Fall Marathon.
