Total funds raised for good causes by Prudential RideLondon cycling events fell by £1.5m last year, new figures show.
Organisers said in a statement today that £11.5m was raised through the 2019 event, down from the record £13m that was reached in the previous year.
The 2019 figure is also down on the £12.8m raised for good causes in 2017.
About 30,000 people took part in the three mass-participation sportives that were held over 19 miles, 46 miles and 100 miles in August last year.
The latest donations bring the total raised for good causes to more than £77m since the event began in 2013.
Hugh Brasher, event director of Prudential RideLondon, said there was no single reason why the overall fundraising total had fallen.
"The 2019 figure was down on the record £13m raised in 2018, but this total still makes the Sunday of Prudential RideLondon the biggest one-day cycling fundraising event in the world," he said.
"Totals do vary year on year, and we knew from our fundraising tracking that the record would not be broken in 2019 because there was a slight fall in the average sum raised per rider and a slight drop in the number of riders raising money for charity.
"It is, of course, never easy to break records."
The Alzheimer’s Society, which was the official charity partner of the 100-mile event, raised the most, with more than £450,000 in 2019.
Prevent Breast Cancer, the charity partner for the 46-mile event, raised more than £122,000.
More than 50 charities have guaranteed places at RideLondon.
The deadline to enter the ballot for places in this year’s Prudential RideLondon-Surrey 100, which is the longest of the public events held over the course of the weekend and takes place on 16 August, is 5pm tomorrow.
