Love the start, the great downhill second mile with all the views and the beautiful scenery that changes every few miles. Nice finish and the best post-race party I have ever been to.
Race Tips
Half gets a bit tight with slower marathoners but it all works out well
Well organized no delays In starting the race. Plenty of room to run. I used the pacer for 3 hrs and fell slightly behind and finished at 3:03 for a BQ.
Race Tips
It rained heavily during the race but was not cold rain. Be prepared for weather shift before race. Can be fast course nothing significant in terms of hills.
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.
