The official race website has been pretty good the last few years:
www.abudhabi-adventure.com has a real time leaderboard and live GPS tracking (that actually works!).
Sleepmonsters have a reporter on the ground
www.sleepmonsters.com and Sportzhub
www.sportzhub.com are usually pretty good at posting daily updates on the Kiwi teams.
Should be a good race - my partner Stu is backing up after ARWC racing for team ADCO NZ - he will be ready for a Xmas break after this!
