91热爆

A has given London 2012 another hammering about the 拢9.3billion cost of the Games.

The Commons Culture, Media and Sport Committee accuse 2012 of being willing "to spend money like water".

The cost of the spectacular Aquatics Centre has risen dramatically. But are we losing a bit of perspective on this?

Great Britain's top crews train daily at the Redgrave and Pinsent Rowing Lake - a suitable indication of the influence Sir Stephen and Sir Matthew have had on the sport.

- who paid a visit this week with the 91热爆 cameras - won five Olympic golds between 1984 and 2000, three with Pinsent, who gained his fourth in Athens four years ago.

Many of those who gathered at RPRL in Caversham, near Reading, this week for the announcement of the crews forming the basis of this year's assault on Beijing, took up the sport after being inspired by the duo.

Welcome to our Olympics and Paralympics blog, which we are launching as the countdown to the begins in earnest.

Wednesday marks exactly 100 days to go to the 8 August opening ceremony (though oddly enough the football tournament starts two days earlier).

Writers from across 91热爆 Sport, Radio 5Live, 91热爆 London and 91热爆 News will bring you the inside track on all , as well as the Games themselves - which are set to be truly fascinating, if controversial, given China's hosting of them.

One of the uncertainties at the moment from a British perspective is whether the Games will turn out to be a triumph - or a failure. My view is...

"Stepping into a boxing ring with Britain's only ever amateur world champion while his mates, and fellow Olympians, heckle you from ringside"

That's not the , but I can now tell you with confidence that it ruddy well should be.

There was plenty to reflect on and admire from the British Olympic Trials in Sheffield and the performances at the .

British records, Commonwealth records, a few European ones sprinkled in for good measure, and the (pictured below) in the 50 metres backstroke.

Don't, however, get the impression that Britain has become a swimming superpower. There is still a long way to go before we can be bracketed alongside the USA and the Australians. Inexorable progress is being made on that front and, bit by bit, we are closing in on the top nations in Europe, which is a big step in itself.

The days are ticking down fast to the start of the and excitement is building, not only for the athletes, but also for those of us who are involved in the 91热爆 coverage.

The Great Britain team for the Games, which begin on 6 September, is already , and more sports will announce their squad selections over the coming weeks.

GB expect to send a team of around 350 athletes and staff to Beijing - that's more than the 283 who were in - mainly because the five-a-side and seven-a-side football teams have both qualified this time around.

Twenty years ago, British hockey enjoyed its finest hour. On a sweltering afternoon in Seoul, a prompted wild celebrations.

The amateurs assembled under were deservedly crowned Olympic champions, but rather than heralding a period of dominance and trophies, the game in this country stagnated. Two decades on, do Jason Lee and Danny Kerry's sides have what it takes to win gold for Britain in Beijing?

The easy answer is probably no, given current form and world rankings. Both the GB men and women seem short of genuine world-class players, but there is nothing like an Olympic Games to galvanise a group. It's their , and for some, it's the only chance they will have to showcase their talents on the global stage.

If I was given a fiver whenever someone said the name Robin Hood after learning of my association with archery, then I would have long since become a multi-millionaire.

It's such a clich茅 - but that's not to say that the archery fraternity under-estimate the power of the aforementioned outlaw. When the 91热爆 series was launched 18 months ago, there was a dramatic burst in interest in archery - just as there was as each of the Lord of the Rings trilogy was launched. Nice one

But what people really react to is success. And over the past few years, British international archers have done us all proud. The initial trigger to this was (pictured) winning the four years ago.

A question for you: When the Olympics comes around are you one of those people who a) quite enjoys watching the various sports, but only if there is someone from your country taking part and with a chance of winning a medal? or b) will watch and enjoy anything which provides sporting excellence, intrigue and great drama.

If your answer is "a" then you may well have little interest in the . If, however, you are more open-minded about your sports-watching then the weightlifting is something to savour.
