If you took part in the Prudential RideLondon-Surrey 100 last month and fancy having another crack next year, or feel inspired by TV coverage to give it a go for the first time, online registration is now open for 2017.

Returning for a fifth year, next year’s event takes place on Sunday 30 July, with organisers saying that the precise route will be confirmed after they have conducted a review of the latest edition.

Online registration can be done at www.PrudentialRideLondon.co.uk, with the system remaining open until 80,000 people have registered or until Friday 6 January 2017, whichever happens first. The entry fee remains £58.

Registration for the shorter Prudential RideLondon-Surrey 46, which made its debut this year, will open on 1 March 2017.

A new feature introduced for 2017 builds on the recent Fixing Dad documentary made by Anthony and Ian Whitington as they persuaded their “extremely stubborn” 63-year-old father Geoff, diagnosed with Type 2 diabetes, to completely overhaul his lifestyle.

Besides changing his diet, he also trained for and rode the 100-mile sportive last weekend, as did his two sons, and the family is now looking to help others in a similar position.

People entering the ballot for places next year will have the option of entering the 2017 Prudential RideLondon Fixing Challenge, and up to four will be selected to be advised by the Whitington family and a team of experts on issues such as diet and lifestyle.

They will also be featured on BBC Get Inspired as well as during the broadcaster’s coverage of next year’s event.

Anthony Whitington said: “In 2017, we could be Fixing Mum, Fixing Dad, Fixing your brother, sister, friend or Fixing you.

“We know how committing to a challenge like this can make a profound and permanent difference to your health and lifestyle and we would love to help other families achieve what our family has done.”

Event director Hugh Brasher commented: “Fixing Dad could be the story of millions of families in the UK today.

“It’s a very human and truly inspirational film with the laughter, tears and arguments of family life which we all know well.

“Poor eating habits and sedentary lifestyle are two of the root causes of the global obesity crisis. In the UK alone, diet-related type 2 diabetes causes hundreds of thousands of premature deaths and treating the condition places a huge burden on the NHS.

“The Fixing Challenge offers four families the chance to transform their lives with the help of the Whitington brothers and, on the way, will create more inspirational films to help other families. We are proud to support this,” he added.
