Montrealers Laurie Comtois and Martin Dupuis are cycling to Vancouver to raise money for Alzheimer's research.

Comtois and Dupuis are selling kilometers for five dollars each - with a goal of donating $25,000 to the cause.

The two young cyclists left Montreal on June 30th and expect to reach Vancouver at the end of August.

Comtois says she is riding in memory of her grandmother.
