Biking around London is very convenient! There are plenty of bike roads and drivers take good care of bikers in general (just as they do with everyone).
But leaving your bike behind for a longer period might be a bad idea just as it is in every big city :)
Equipment: Bike and raincoat
Well it does help if you actually turn the pedals!
Some of London's Parks (especially Hyde Park) are so large, it is possible to cycle around inside them for a while without covering too much of the same area too many times.
There's also the Serpentine lake to ride around as you can see in this picture.
I wouldn't recommend cycling round London's roads too much though unless you have a death wish or are a little unhinged!
Equipment: A bike and something to lock it up with if you stop anywhere
London is a superb place to cycle.
There are plenty of paths and the scenery is gorgeous (unless you are a commuter cycler!).
Nothing beats exercising out in nature! No smoggy streets and noisy (and rude!) traffic needed.. just a quiet lane in a nearby common or park.
You do share your cycle lanes with pedestrians, dogs, other bikes and horses, but hey.. a FAR better traffic scenario isnt it??
One can hire bikes at various spots in the City.
London once had its own motor racing circuit, actually located within the Crystal Palace park complex...
The first race, for motorcycles, took place on 27th May 1927
The track was only a mile long, with a mixture of hardpack on the straights, but tarmac bends, & this layout was utilised until it was extended by another mile & properly surfaced in December 1936
The London Grand Prix was staged on the newly laid-out circuit in July 1937 - the winner was Prince Bira in his famous ERA
Bira won again when racing returned later that year, which happened to be the first ever motor race televised by the BBC...
During the war period, the park was used by the Ministry 0f Defence, & when the circuit was re-opened, it was reduced to only 1.4miles, mainly because of complaints from neighbours over noise...
Noise was an issue that hindered development of the circuit, & its use was limited to 14 days per year, until the final meeting on 23rd September 1972
By then, racing cars had outgrown the track layout, & despite efforts to instal barriers & run-off areas, the confines of Crystal Palace park limited what could be done to keep the circuit abreast of safety issues...
The only posthumous world champion, in the history of F1 - Jochen Rindt, drove an average lap speed in excess of 100mph, for the first time at Crystal Palace, in 1970 (- the same year he was killed at Monza, but still awarded the world championship...)
Principlr forms of motor sport hels at Crystal Palace, include;
F1 (non-championship) Mike Hailwood took the final lap record in May 1972
Although the circuit is no longer suitable for motor sports, Sevenoaks & District Motor Club have arranged sprintit days there, beginning in 1997
Since then, it has become the cycle track around Crystal Palace park, & is usually in use by club members on a Tuesday evening...
Televised footage from the tracks heyday, includes film from 1971 - production saloon car racing, featuring a fierce battle between Frank Williams & Eddie Jordan - 2 men who would become famous for the F1 teams bearing their surnames...
Crystal Palace circuit was also used as a filming location in the Italian Job (- remember Michael Caine; "YOU WERE ONLY SUPPOSED TO BLOW THE BLOODY DOORS OFF!")
Talk continues about London staging a F1 World Championship status GP - & F1 cars have been demonstrated in central London - an event that received a crowd out of all proportion to that expected...
0ther principle cities, such as Moscow & New York, have also been linked to Bernie Ecclestone's empire, by business ventures intended to stage F1 racing, but these never come to fruition...
My opinion is that, Britain is already spoilt for choice for quality, specialist motor racing venues, so why create a compromised 1 ?
Street circuits provide limited spectator access & are usually too narrow to allow proper racing - Birmingham used to stage its Super Prix for F2/F3000 cars, an event which was really a high-speed procession, interupted by inevitable collisions...
Will London ever hold a GP again?
I'll believe it if it happens...
