In April of this year Will Holroyd, Harrods Aviation sales and marketing director, will be tackling his toughest personal physical challenge to date. He plans to run the Brighton Marathon one Sunday followed by the world famous London Marathon the next.

"I reach the grand age of 40 this year and wanted to celebrate this milestone by doing something I would remember for ever," says Holroyd. "I also wanted to see if I could raise as much money as possible for a great charity. I chose the UK-based charity Whizz-Kidz as I believe they make a real, long lasting difference to the lives of thousands of disabled children.

"The biggest challenge is that I have given up drinking for four months to help with the training, so that's a sober NBAA IOC and Cannes for me this year."

Holroyd is appealing to all his aviation friends to consider making a donation in support of the 52.2 miles he will be running, and the hundreds of early morning hours he will be putting in during the training. Visit http://uk.virginmoneygiving.com/ WillHolroyd
