2018 race entries are now open!!! Looks like an awesome route this year, Rig Road, K1, QAA line with the longest single day in the race history at over 140kms... Sounds like an epic ride...what are you waiting for? http://desertchallenge.org
Day 3, after passing the salt lakes, looks like it heads up K1 -in the Swale, northerly, so with any luck a tail wind to push you home...while a long day, could be fast! If there is a head wind across the salt lakes - better pair up and ride peloton!!!
Riding north to the lone gum last year was a really enjoyable ride, if you like hot and sandy! (Jokes aside, it was a really good day.)
This years race looks like it might take in Poeppel Corner and does Big and Little Red... Great landmarks!
