There was a group of 8 of us that ran the Half this past December and 3 that ran the 10k.
It was an AWESOME time! Very well organized and the after party was fantastic.
Race started at 5:15 so still dark and not as hot, once the sun was up though it got pretty warm.
Running the 10k you should be crossing the finish line before the sun is completely up over the mountains.
Lesson learned ........ do not think a week prior of rum and red-stripe drinking will hydrate you :)
There are shuttles that start at the roundabout that start at about 4:15 am and run quite frequently. Just stand on the road outside your hotel and they will stop for you.
We were staying up on the cliffs so had to arrange for a taxi for 4:30 am to take us to the roundabout, poor guy slept in the parking lot at the hotel so he wouldn't be late to pick us up.
