Organisers ensured all safety precautions were in place to ensure safe passage for the 228km journey along the Gwydir Highway from JJ Lawrence Park in South Grafton.
"The real importance is for all riders to be safe and share the road with other users," race commissaire Stuart McPherson said.
"It's a long day but should be an enjoyable day although it is a bit damp here this morning."
