Amy Gillett Foundation creator Simon Gillett said its 30 riders raised more than $300,000 for the foundation, which works towards having no cyclists die on the road.
The tour, named after Mr Gillett's wife who died in an on-road cycling accident in Germany in 2005, started in Devonport on December 2 before heading to Cradle Mountain via Penguin.
The group then visited Bronte Lagoon in the central highlands before riding on to Hobart, Coles Bay, St Helens and Launceston.
The Amy Gillett Foundation requests drivers leave a metre between their cars and cyclists.
``We were really impressed with drivers,'' Mr Gillett said.
``We're slowly turning the tide.''
The regular Targa participant and Melbourne resident said it was a pleasure to enjoy the scenery from the seat of his BMC.
Riders in Amy's Share the Road tour included Brad McGee, Wes Sulzberger, Stephen Hodge and Koen de Kort.
