The Ride is the BHF's biggest fundraising event of the year, and is the biggest bike ride in Europe.
It's so popular that applications from thousands of cyclists to take part have to be turned down - restrictions ensuring that roads aren't too overcrowded.
Since it started in 1980, the event has raised more than ?35 million for the charity and has attracted more than 650,000 riders.
It's the money raised through getting sponsored that will really help to make the difference to our research. As a charity, we depend on fundraising to help us save lives.
