review of 2016 Western Pacific Marathon.   

5 / 5 Stars


The course was great - really flat - and also super beautiful. Some stretches were very long and straight, and could get a little tedious, but overall an enjoyable run. After the run there was a huge spread of food and all the volunteers were super helpful and cheerful.
