Well, I was impressed

I am inpressed, too. Perhaps cycle computers could have a pause
button so that an un-red average could be maintained?

They mostly do stop the clock when you stop. But you will still lose
time for a red light because you have to slow down and get back up to
speed.

Of course there is another way to maintain average speed through red
lights ...

Congrats on the good time.

Many computers pause whilst you are stopped, but the actual time lost
whilst stopped is unclear. You loose some time slowing down, and then
accelerating away from the traffic lights. On the other hand whilst
slowing down and stopped, you get a chance for a breather, which allows
you to pedal harder when the lights go green.

Currently I time the whole journey with my camera, and the moving time
with the computer.

Proceed at a constant 0 mph for the entire length of your journey?

Riding to work this morning, I happened to glance at my average speed
reading: 19.7mph! Regrettably, had to stop at a traffic light and
lost 0.5mph on arriving at work. This journey usually gives 17.5-or-
so, depending on prevailing traffic conditions. It's over 2 years
since I got something really high (18.8). Don't think I'll be able to
beat that tomorrow!

Good effort! My average commuting speed is probably way below that,
but I did clock a top-speed of 51.2Mph on Brian Rourke's Cat & Fiddle
run yesterday. Not bad credentials for a Mountain Bike* I thought.
What's the fastest speeds people here have recorded?

Well my Garmin regularly has me pedalling at well over 200mph for very
short intervals when I teleport a mile or two then back again in an
instant. I have tried to tell them this is down to their bad maths in
rather than satellite signals to no avail.

Sounds familiar, mines clocked walking at a pretty impressive 60+ Mph
around Snowdon before now. I think we can safely discount these
events as false positives. But I trust the 51.2 though.

44.2mph for me on a fully loaded tourer (I'm not exactly light either)
heading down Llancloudy Hill south of Hereford. The run down from Bristol
airport into the city centre was pretty damn good too, 40+mph sustained for
4 miles. What a rush!

People are obviously much better at getting into a good tuck than me[1] :-(

I've managed 49.9mph and spun out. As soon as I stopped pedalling I
started slowing down again. Quick calculation shows my cadence was in
the 170-180 range. I'm now getting too old and around 45mph I start
getting scared :-(

A few Sundays ago I managed 56.3kph on the Brompton in the Euston Road
underpass. Unfortunately I didn't realize until I was almost at the
bottom that I was going to set a new top speed on the Brompton so I
didn't start pushing hard early enough. I was still doing 48kph when I'd
climbed out again although I then had to slow down for traffic and
traffic lights.

Tim.

[1] or perhaps it's just that I'm not very big and weight is a big
advantage when descending.

Fastest official computer recorded speed for me is a mere 37 mph on a
Birdy, dreadfully slow compared to some on here. My excuse is that
there are very few long sustained downhills in the SE.

I have descended this road on the Birdy and it felt very scary but I
didn't have a record of the peak speed:

http://www.streetmap.co.uk/newmap.srf?x=402105&y=392280&z=4&sv=402105,392280&st=4&ar=Y&mapp=newmap.srf&searchp=newsearch.srf

I must admit I am nervous of fast descents. I am always worried that
something is going to run out in front of me or I am going to hit a
pothole and come off.

Duncan Smith said:

My wife and I have managed approx 47mph on our tandem (cannot remember
the exact figure). That was quite scary, and we ran out of gears.

Personnally, on individual bikes, I am not particularly good at
getting a high top speed (I struggle over about 28mph, even down
hills), but go for maintaining a high average. My wife on the other
hand can achieve well over 30mph on some of our local hills, but
cannot maintain speed on the flat in the same way.

My Cateye Velo 5, used on a Raleigh Sports, regularly gives readings
in excess of 150mph, but although it *feels* like I'm working that
hard, I rather suspect that the cyclo-computer is subject to some
interference! My son's Velo 5 and our various Velo 8s are not prone
to false readings, just the one.

The computer on our tandem showed 75kph when I and it stopped sliding
down the road.

Use a stick with a magnet on the end and keep taping the sensor
while waiting at the lights?

Or put two or three magnets on your wheel and not worry about the
average dropping at lights?

I've done about 50mph down Rownham Hill, and quite frankly kakked myself
when that wall on the corner was getting too bl**dy close for comfort (I
wasn't doing 50 on that bit, BTW!). I've also done similar speeds on
the road dropping down into Looe from the Polperro direction when I
lived thataway.

Now that I've grown up :-) and realised that I don't bounce any more I
was really chuffed to have reached 37.2mph on my MTB!

I've done 51 three times, all touring.

One west of Pamplona. Super surface, long descent, one into Trentino,
long descent on which a pal did 56! and one on a country road in
Catalunya.
I've done 45 numerous times, even on a MTB.

Not a good idea though to go very fast

You should hit at least 40 coming down the hill on Rusper road.

My mate Chris had a reading of 55mph on his speedo when I overtook him
on a long descent in Snowdonia in 1989. By this point, neither Chris nor
myself dared to touch the brakes.

The real fun came when we both overtook a Porsche.

Luke
