Based in St. Albans in the Hawkesbury Valley, the Dirt Works 100km endurance race is scheduled for May 6. Its course follows the historic Great North Road through the Dharug and Yengo National Parks, located two hours northwest of Sydney. The 100km course has 32% singletrack, 44% fire trail, 16% dirt road, and 8% tarmac, although one infamous hike-a-bike has been replaced with a more ride-able climb up Webbs creek hill. A shorter 50km course is also an option.
The event was so popular in 2006 that organizers compiled a waiting list of over 100 riders after race entries sold out one month before race day. To accommodate increased demand, the field size has been increased 25% for 2007 to 1000 participants. However, 30% of the race entries were already sold within one week of registration opening for 2007.
