A friend of tragic Monmouth teenager Jack McKenzie is planning a skydive to raise money for charity in his name.

Ffion Coffey will make the daring jump from 13,000ft later this month in memory of Jack, who was killed in a car crash in Herefordshire in September 2010.

In doing so, she is hoping to raise £500 for the road safety charity Brake, which produces educational literature and runs community programmes and events including Road Safety Week in November.

Ffion, who works at the Orange shop in Monmouth, said: "I am doing the skydive because I find the thought of it terrifying and wanted to do the scariest thing to raise the most amount of money.

"I'm scared of heights but I will definitely do it, I'm just trying not to think about it too much."

Harriet Barton, Abigail Bowsher and Sophie Grey, all friends of Jack's, recently completed a 100-mile bike ride in Pembrokeshire, raising £600. Money donated to Brake in Jack's name will be used to help fund the charity's 2young2die campaign.

It is being led by young people and aims to help reduce deaths and casualties on our roads by getting young people actively engaged in learning about and promoting road safety.

One of the key ways in which it works is through low-cost courses to train volunteer ambassadors – who might include community campaigners, teachers, youth workers, road safety officers and emergency services personnel – to run interactive workshops with young people that stimulate discussions and campaigning activity.

Young people are also encouraged to explore road safety issues and spread life-saving messages via the 2young2die awards scheme, which recognises and rewards teams of young people that produce the most effective and innovative road safety campaigns, such as creating videos, running awareness raising events or producing poster campaigns.

Rich Andrew, the charity's senior development officer, said: "Brake is extremely grateful to the friends and family of Jack McKenzie for going to such great lengths to support our work.

"Their efforts are not only a fitting tribute to Jack but are also an inspirational way to highlight issues around road safety, especially among young people, for whom national casualty figures are especially high.

"The funds that they are generously raising will help Brake to continue spreading life-saving and educational road safety messages through initiatives such as the 2young2die campaign and helping to support people affected by road crashes.
