Only 7 weeks to get ready for this one !!
Provisional route has been posted on bikeSA site - and a mapmyride attempt to map it here :

Route is subject to change between now and then.
I am not going to make any uninformed comments this time about how flat the route looks - haha -

Loop 1 covers typically spectacular Adelaide Hills areas, looking fwd to that section.
Be careful traversing Mt Barker - it gets pretty congested on the main road and roundabout through there, and the local motorists are not always cyclist friendly.
Loop 2 - a wonderful high speed descent for 20km through to Wistow .. should be a good opportunity to get the avg speed up. And then a 20km grind to climb back to Nairne. That road to Nairne is perfectly positioned to benefit from a tailwind, if current wind patterns keep up.
Im aiming for anything under 3hrs20mins on this one as a great time. Comments ?
