Doesn't seem like a bad sportif ride.
There are several different options on the website which is slightly outdated. I would prefer optional food stops rather than enforced ones.130km cycle from Taronga Western Plains Zoo, Dubbo to Yeoval and back.
Cyclists leave Taronga Western Plains Zoo and ride along Obley Road the 65km to Yeoval, arriving at 9.30am, meeting the Sydney riders for a coffee and bacon and egg roll.
At 10.00am all the cyclists will cycle the 35km to "Wambangalang Environmental School", arriving at 11.30am, where morning tea will be served.
At 12.00pm all cyclists will cycle the 30km to Taronga Western Plains Zoo, arriving at 1.15pm. After completing a lap of the Zoo, the cyclists will enjoy a BBQ lunch and refreshments in front of the Savannah Room at the Zoo.
Mainly I was interested if it was all asphalt road as it doesn't say online.
