Andy Lewis said:[PS: I did briefly consider coming along the southern bank but it's
far too fiddly.]
Over the years I've tried both and there's not much in it - coming into
town (i.e. City-ish) from the south-west (Putney, Barnes, etc.) I've
tried south of the river (York Road, Nine Elms, Vauxhall Cross,
Waterloo, over Southwark) or north (over Putney Bridge, Kings Road,
Embankment) and all manner of variations in between.
I must say that the ride back from Blackfriars, down the Embankment,
around Parliament Square, continuing past the Tate, and from then on to
the Kings Road down towards the south-west is one of my favourite routes
in London - generally quite fast, plenty of opportunity for meeting
other cyclists and racing/drafting, and since the congestion charge most
of it isn't as hair-rasingly dangerous or busy as it used to be, either.
I tend to stick to the roads avoiding the 'facilities' where they exist
(e.g. on Nine Elms Lane), while they require more attention (i.e. they
are more dangerous), you can maintain higher speeds (notwithstanding the
regular rests at the lights).
Like anything, once you learn the route, what seemed fiddly becomes
second nature, then you play with it to shave a few metres and seconds
off and you're learning more routes ... you'll be able to do The
Knowledge soon enough.
