Race goers struggle to keep their hats on in strong winds on the fourth day at Royal Ascot, southwest of London, on June 22.
Reuters reports -- Ladies, forget those flimsy fascinators and get yourself a proper hat: one that has a base of at least 4 inches in diameter.
So says a new dress code coming into force at this year's Royal Ascot, the annual horse-race meeting attended by Britain's Queen Elizabeth and a highlight of high society's summer season.
"Strapless, off-the-shoulder, halter-neck, spaghetti straps and dresses with a strap of less than 1 inch (2.5cm) are not permitted," says the dress code for lady racegoers lucky enough to have tickets for the exclusive Royal Enclosure.

A competitor emerges from muddy water during the Tough Guy Challenge endurance race on Jan. 29, in Telford, England. Every year thousands of people run the 8 mile assault course which involves freezing temperatures, fire and ice.
I think that the Tough Guy site answers the question best as to what the race is all about:
Tough Guy™ is the nightmare of being chased by a herd of stallions.
Your only escape route is a mighty and revered obstacle course. Built from trees, 15 metres high with Tarzan ropes swinging. No hats and no hook ups. Just pure, organic grip strength from your cold and wet hands.
Belly flop beneath razor wire, the stallions still snorting at your heels, matching your every step. Look deep into the flames before diving through them straight into shoe sucking mud. Then something wakes you, or does it? Were the stallions just a nightmare?
No time to look back, the narrow tunnels beckon. You bravely enter to discover they're filled with murky water. You can't see. You can't breathe. What chance of survival? Grope around and grab that rope. Pull yourself lungs bursting, into the light! You see the sun, or is it just another cruel mirage?
You are faced with a wall climb, as high as a mountain. No visibility again. Is that smoke, mist or cloud? How do you get down? Take the netting or dive into the freezing lake. You suddenly realise that the sound of stallions behind is fading. You must go on. The only route is through the Arctic water.
A monkey rope, a barbed wire crawl, a rubber snake, a skin ripping snake, you can smell the finish. It's familiar.....you recognise.....it smells like.....cocoa! You know you've earned it!

A musher and his dogs compete on a track near the Mont-Cenis Path during the ninth stage of La Grande Odyssee sled dogs race on Jan. 17, 2012. The race crosses the Alps in France covering 621 mile over 11 days. This picture was taken with a long exposure and a fisheye lens.
Onthesnow.com reports, that 'the most difficult dog and sled race in the world" is currently being run in the Alps. La Grande Odyssey crosses the Alps in 11 stages and covers more than 620 miles. The mushers are the best in the world, from 11 different countries.
Given the news lately, it's nice to see that these racial epithets are finally being removed.
AP reports:
SACRAMENTO, Calif. — Workers on Tuesday began installing new markers at a public cemetery near Sacramento where relocated Gold Rush-era gravestones had been marked with the N-word.
California prison inmates who are part of a work program were placing granite headstones on many of the 36 graves at the Mormon Island Relocation Cemetery near Folsom, about 25 miles east of the state capital.
The U.S. Army Corps of Engineers relocated the graves from a site a few miles away known as Negro Hill to build Folsom Dam in 1954. The N-word was chiseled into the new markers, and activists have long sought for them to be replaced.

Steven Abujen, an California prison inmate with the Prison Industry Authority, cleans one of the newly installed headstones that is replacing one of the offensive markers bearing the n-word at the Mormon Island Relocation Cemetery, near Folsom, Calif., Tuesday, Oct. 18. In 1954, the U.S. Army Corp of Engineers had the remains of 36 bodies buried at the Gold Rush-era Negro Hill Cemetery moved to construct Folsom Lake. When the bodies were moved, the graves were marked by stones with a derogatory term for African-American. Now, some 60 years later the offensive markers are being replaced with newly made granite stones.
