For nine years, Wantirna South mother Caroline Bourke has taken part in the RACV Great Victorian Bike Ride.
The keen cyclist says she's seen a lot since first taking part in 2004.
"It's great just getting outside and seeing Victoria from the seat of a bike."
More than 4000 riders are expected to join Ms Bourke on the nine-day trip through Gippsland on one of the biggest cycling holidays in the world.
She advises riders to be prepared. "If you are thinking about doing it for the first time. you need to put some miles into the saddle. Do the training."
