Hi Patrick,
This is my favorite marathon course to run, wish I could run it with you next week (hmm what am I doing next week ...).
Here are suggestions:
1. I hate waking up early to catch buses to the start of the races. If you are staying in Ojai great. If you are staying in Ventura/Oxnard you can get dropped off near the start by avoiding the main road into Ojai and it only takes 20 minutes.
2. Follow a pace group. The locals do their best for crowd support but it's a lonely race. They have a 3:02 group which given the latest BQ cut-off they will probably run a little more aggressive or at least a pack will splinter off early.
3. The bike path for the downhill has a lot of camber. Look for the flattest portion to run on. If you are feeling something in you hips turn a little to the right or left a little to try to stretch it out while you are running. You will also appreciate some of the scenery that you miss by looking forward.
4. Run the tangents. There are a lot of twists and turns. And if you run it well you should be a little short on your GPS.
5. Watch out for the divots from missing reflectors in the middle of the road around mile 15-20. Watch out for the metal post in the bike lane before an intersection.
6. After mile 19-20, you will go from 2% to 1% drop in grade. That will feel really hard. Stay as long as possible with the pace group or it will get really lonely.
7. It also gets warm at the end. Make sure you get fluids/electrolytes in early.
Also for places to eat, I would recommend Cafe Fiore if you pasta the night before and the Aloha Steakhouse which is near the finish for the post-race.
Hope this helps. Good luck.
