400 miles. 1 week. That's the challenge for Sky Sports News presenters Julian Waters and Rob Wotton. Supported by specialist cycle trip company Love Velo, they will be cycling from St James Park in Exeter to St James' Park in Newcastle.
Rob and Julian set off on July 8th, and arrive on July 14th, providing the wind is behind them.
Rob and Julian are raising funds for Rett Syndrome Research Trust UK and will be well supported by their colleagues.
Fellow SSN presenter OIivia Godfrey will be leading their support team, while many other colleagues at Sky Sports News - including the great Jim White, Clare Tomlinson and Charlie Webster - will also be cycling various legs. Plus they will be supported by leading figures from the sporting world like Ian Dowie, Phil Neville, Dave Brailsford and Lee Briers.
It is a grueling trip but it is nothing compared to the hardships girls like Dylan go through every day.
Dylan has recently been diagnosed with Rett Syndrome. She is only two years old but has already been condemned to a life of profound disability and physical pain. She can no longer walk, talk or use her hands. In time, she will lose the ability to eat, drink, even breathe.
But incredibly and against all the odds she can be saved. Rett Syndrome has been REVERSED in the lab. All we need is money to translate this amazing breakthrough into clinical treatments for Dylan and hundreds of thousands of girls like her.
One such girl is Beth Stevenson - daughter of Andy Stevenson - who will be cycling with us. Andy is co-founder of Rett Syndrome Research Trust UK - the charity which is driving this research forward. He knows first-hand what it is like to watch your child degenerate in front of your eyes.
So please help Beth, help Dylan and all the girls living with Rett Syndrome. A cure is within reach - but time is against them.
