My mate is organising this event on his local trails: http://www.xcracer.com/raceentry/viewevent.php?event_id=316
From the weblink:
"The course will be made up using all the classic XC race trails that have been used in the park over the past decade or more with some new sections being worked on specially for the event.
Racers can expect a mix of steep, fast descents with more than a fair share of technical climbing, making it an excellent, fun and interesting course to race on. The proposed route is 11km long with up to 450m ascent per lap."
Sounds tough but really good. Might be a nice end of season close event. Hope the rain stays off!
