The biggest bike ride in Europe rolls into town on Sunday (17 June).
Almost 30,000 cyclists are expected, many of them joined on the day by friends and family.
Most of those taking part raise money for charity, with the British Heart Foundation (BHF) being the main beneficiary.
The event has become so popular that it has spawned two spin-offs. One, the London to Brighton night bike ride, was held for the first time just over a fortnight ago, and an off-road version is scheduled for September.
Almost 5,000 cyclists took part in the night bike ride.
Some were disappointed when they made their way to Brighton railway station to try to go home.
They were told that bikes were not being allowed on trains.
While the organisers had laid on transport for people going back to London – by road – several cyclists were unaware that they faced a ban on the trains.
The situation has become familiar for those taking part in the main event.
For more than 20 years thousands went home on the train. But when the last of the old slam-door trains were replaced seven years ago, in came the ban.
The response from the British Heart Foundation has been pragmatic. It lays on a shuttle service with lorries to transport bikes and something more suitable for the saddle sore.
Becky Reynolds, from the campaign group Bricycles, said: “We were deeply disappointed when there was no longer a train service available for cyclists.
“The arrangements with the big lorries on the seafront and the masses of bubble wrap are not ideal.
“We would like to see a sustainable solution. It’s not just the cyclists who take part in the bike ride who are affected by the ban on the trains, it’s all the other leisure cyclists across the area.
“Brighton is a destination for loads of events.”
She said that other rail operators managed to cope with mass bike rides although she acknowledged that the annual BHF London to Brighton bike ride was the biggest.
