review of 2016 OC Marathon.   

5 / 5 Stars


The course has a great downhill first half, goes through a number of cities in Orange County and the views and terrain changes about every three miles. The weather is almost always perfect running weather and the party at the end is the best.

Race Tips

Great PR course. First half has the beauty, the second half is just flat and fast.
