As cyclists scramble to prepare for Saturday's River2Reef ride, the region's roads have been chock-a-block with riders pushing their pedals, gearing up for the big day.
Almost 1100 riders of all levels of fitness have registered for the ride, 300 more than last year.
One such cyclephant is Danny McCarthy, a giant of a rider who has put in a Herculean effort over the past few weeks.
With the option of four ride distances on the day, 35km, 60km, 90km and 135km, Mr McCarthy is eyeing off the big one. A gruelling training regime over the past month has resulted in his riding more than 1000km, about the same as cycling from Mackay to Brisbane.
Backing off the schedule in the final countdown to Saturday's event, Mr McCarthy said he was "only riding about 40km per day" for the remainder of the week.
"Friday morning will pull me up and I won't ride for a whole day," he said.
"I'll stay home and clean my bike instead."
After spending so many hours on the bike, he said most motorists were considerate of Mackay's booming number of two-wheeled warriors.
The most important rule, he said, was for drivers to give riders a metre and a half of space.
Funds raised in the not-for-profit charity event go to CQ-RACQ Rescue and Mackay Sporting Wheelies.
