Random London Fact of the Day

The London Underground is a source of strife and anguish for many daily London commuters, however, in the 19th century there were licensed bars, often on the underground platforms themselves. Good for the commuters, perhaps, but spare a thought for the poor barmaid who worked down there. A pamphlet entitled Inquiries concerning Female Labour in the Metropolis, published in 1889, articulates the tribulations of these barmaids:

'Of all barmaids these girls are most to be pitied. Draughts, bad atmosphere, and sulphurous smoke give them sore throats and heart complaints. Not a few of them stand from seventy-six to eighty-six hours in the week, or about eleven hours a day. They work in shifts, coming on early in the morning, and working with stated intervals until midnight. One Sunday in the month is considered ample time for recreation.'

Good Cause of the Day

The Ellen MacArthur Cancer Trust is a scheme which takes young people who have suffered from cancer, leukaemia or other serious illnesses and helps them on their route to recovery through the fantastic experience of sailing. They work with every young persons' primary cancer care unit in the UK and aim to help these young people by increasing their independence, sense of control and confidence.

With the Ellen MacArthur Cancer Trust and Barretstown, a charity which supports children with serious illnesses and their families, you could have to chance to visit the top of the BT Tower and enjoy the stunning views from its 34th floor window. Each ticket costs £50 and includes the exhilarating 189 metre lift ride, bubbly and refreshments at the top, and of course the most wonderful 360° views of the London skyline. Most importantly, all money raised will be split between the two charities, both of which do incredible work.

The BBC are hedging their bets today with an icon to cover most weather eventualities. If you're a betting person, your money is probably safe if you back Rainy Runner. Though we doubt you'll find a bookie offering good odds. If you want a flutter on an outsider, Missing Sunshine is running at 14:20 at 100-1 against. However, the going is soft with 17mm of rain overnight, and wet conditions have seen Missing Sunshine being a non-runner. Be lucky!
