If you're not one of those on a saddle but still want to get involved, we've detailed the best places to watch.
Where you can watch
RideLondon kicks off on Friday for the first time this year when a crew of BMXers, including daredevil trials cyclist Danny MacAskill, at Lee Valley VeloPark in the Queen Elizabeth Olympic Park.
Entry is free and the action runs until 20.30 at night. Get there by 19.45 to catch the finals of a competition specifically for young BMX-obssessed boy and girl racers aged between eight and 13 which offers up to £600 to the winning team.
The FreeCycle; RideLondon's famous, open-to-everyone stroll through a shutdown central London starts on at 9.00am on Saturday morning.
Registration is now closed, but early risers can watch the proceedings from all good London sightseeing spots; Waterloo Bridge, the Bank of England, St. Paul's Cathedral, Buckingham Palace, the Strand and the Mall.
"Festival zones" with entertainments and activities will be present at Green Park, Aldwych, Lincoln's Inn Fields, Guildhall Festival, Leadenhall Market, St. Paul's and Southbank.
In the evening the top 20 women's racing teams in the world - including Britain's former RideLondon Grand Prix winner Giorgia Bronzini - converge on The Mall in St James's Park at 5pm for the Classique, the richest one day race in the history of women's cycling with a winner's prize of €25,000.
The 5.5km circuit race passes through Big Ben, Whitehall, the Strand and Trafalgar Square where spectators can watch from the side of the street until the race finishes at around 18.45.
Alternatively, if you don't fancy the crowds, you can watch from home on BBC 2.
For light relief, stick around in St. James's Park for 19.15 when over 500 riders of varying ability and outfits take part in the eight-lap circuit Brompton World Championship race on their foldable bikes.
Sunday is when the serious distance races gets started.
At the crack of dawn - 06.00 to be precise - 25,000 riders will set off from the Olympic Park for the London-Surrey 100 sportive. Shortly after, the London-Surrey 46 sportive, a new ride for newer riders unused to a mass participation sportive, will set off. Both sportives finish on the Mall.
