What's the craziest cuppa you've ever had?

Lifeboat Tea, the tea brand that raises funds for the Royal National Lifeboat Institution (RNLI), is launching a fund-raising publicity initiative called Extreme Tea.

Kicking off the activity, 22-year-old Charlie Walker is leaving the UK on 1st July to cycle around the world in a dedicated four-year challenge, providing numerous opportunities for brewing Extreme Tea.

‘Taking tea’ in extreme places and situations is intended get people to recognise the lengths that the volunteer RNLI crew go to whilst most people are safely tucked up at home with a good brew.

Charlie said: “The RNLI is exceptional due to its outstanding level of service and the exceptional bravery of the mostly volunteer crew. The message is simple; ‘drink tea, save lives’.”

Other Extreme Tea drinkers will include Cornish RNLI lifeguard and sprint kayaker Kerry Blewett, who is training with the GB sprint kayak team ahead of the London 2012 Olympics; Emily Sarsfield, the British number one ski-cross athlete; professional stand-up paddle surfer and windsurfer John Hibbard and professional windsurfer James Cox and mountaineer Geordie Stewart.

Lifeboat Tea is inviting people to follow the ambassadors and share photos via the Lifeboat Tea website (www.LifeboatTea.co.uk ), Facebook and Twitter.

A bright orange Lifeboat Tea van will also be on tour around the UK this summer.

Lifeboat Tea raises invaluable funds, with 7p from every pack sold going directly to the RNLI to help train and equip the charity’s dedicated volunteers.

Lifeboat Tea costs £2.09 and is available from leading supermarkets such as Waitrose and selected Tesco and Asda supermarkets. It is also available in RNLI shops.

Williamson Tea is a family owned business with over 140 years of experience in the art of growing, selecting and blending fine teas and has supported the RNLI for over 20 years.
