You are here: London Dating > Speed Dating in London Speed Dating in London Speed Dating is where an equal number of male and female singles attend an organised event with the hope of finding the perfect partner. Most events have between 20-50 people and each 'date' lasts between 3 and 8 minutes. At the end of the date, each party indicates on a scorecard whether they'd like to see that individual again. If both circle yes it's a mutual match and the organizer will send contact information to both parties; if only one of the two parties or neither circles yes, there is no match, and no contact information will be shared.
