Rio Tinto London's local charity for this year is the RNLI Tower Lifeboat Station on the River Thames. The RNLI is entirely funded by charitable donations. To help raise funds I am seeking your support for the challenge of riding from London to Paris in July.

I'll be part of a group of 30 riding from London's Tower Lifeboat station to the finish of this year's Tour de France in Paris.

Cycling to Paris, that's tough!

Donating to the RNLI through JustGiving, that's easy!

It's also fast and totally secure. Your details are safe with JustGiving – they’ll never sell them on or send unwanted emails. Once you donate, they’ll send your money directly to the charity and make sure Gift Aid is reclaimed on every eligible donation by a UK taxpayer. So it’s the most efficient way to donate - I raise more, whilst saving time and cutting costs for the charity.

So please dig deep and donate now.
