The OC Marathon
The Full Marathon course is net downhill in elevation from start to finish. From the start to mile 5 is all downhill. From mile 5 to 9.5, it is flat. At mile 9.5 there is a hill 150 ft. long and 45' in height and at mile 11.5 there is a 1/4 of a mile long incline also 45' in height. There is another another 45' incline at mile 14.5 over the 405 overpass and a 40' incline slightly over 1/4 of a mile in length at mile 23 after leaving Fairview Park. These are all relatively small hills.
