Approximately 250 cyclists will descend on central London on Sunday with yellow ribbons attached to their bikes to demonstrate solidarity with the hostages still held by Hamas.

The route, which will consist of different lengths to accommodate different abilities, will converge and end in the vicinity of the larger rally taking place in central London later in the day, allowing for participation in both.

Professional road cyclist Chris Froome OBE, a member of Israel-Premiere Tech cycling team, will be joining the initiative from Israel.

Organiser of the London leg, Howard Kayman, who previously raised substantial funds for Help for Heroes, had originally hoped for around 20 to 30 participants to sign up, and “never thought” it would attract well over 200.

He said: “There is a large cycling fraternity within the Jewish community, many of whom have participated in fundraising rides for the likes of Norwood, Langdon and other charities over the years, and this initiative really seems to have hit a chord with the cycling community.

"We have been overwhelmed by the level of interest from people from all walks of life, including several peers, and, poignantly, the ride will be led by the father of a tragic victim of the Supernova open-air music festival massacre.”

The event, for which registration closes on Thursday night at 10pm, will be shared on social media using the hashtags #RideToBringThemHomeNow and #BringThemHomeNow.

Participants must register on Eventbrite and bring a copy of entry on the day. Warm clothes are strongly recommended, and a helmet is required. Under 16s must be accompanied by an adult.
