What’s your fastest recorded speed…

Let’s hope we don’t have to make an emergency stop!

I think the effects of that might be rather dramatic!

My fastest known speed was about 48mph, on my first CC forum ride in Mid Wales, coming down towards Machynlleth from the Llanidloes road. I remember a sharp bend at the bottom, and thinking this really was fast enough for me.

Another memorable time I was descending Cleeve Hill in the Cotswolds with a car close behind me, and got speed wobble/shimmy at 42mph. I probably only wobbled for a few seconds until I got the bike back under control, but it shat me up enough that I have consciously avoided reaching that speed ever since.

I thought of this recently when looking at some info on Strava. Living in flat Suffolk is (Mostly ?) the reason my highest recorded / remembered speed was 36.something MPH I think…..

We did ‘find’ a big hill today. And having some energy at that point I did tuck in a bit (Big guy on a flatbar bike) and peddle like a maniac. I’m guessing this must be vaguely true…..🤷‍♂️

A good find, in your neck of the woods! Once you're going fast enough that you can't usefully pedal anymore -usually around 40mph, depending on gearing- it's best to get into the tightest tuck you can safely manage.

I'm too old for it I suppose, but still love flying down hills as fast as I can, like an excitable child😅. I have cracked 60mph only a few times so far, all years ago, gliding down hills on the southern edge of the massif in France. You need either a long fairly steep hill or a good tailwind to get much faster than mid 50's, I've found.

Where I live in Cornwall it's all short steep hills everywhere, so most rides have opportunities for 50 or so, but I haven't found a hill long and straight enough to go much faster here. Still looking though..!

Pretty much agree with all ! I know it’s GPS based and should be something like true……but my previous noted best of 36mph got smashed. And it didn’t feel too different 🤷‍♂️

And yea I’m about as aerodynamic as a House. Head down, Elbows, stomach and everything I can tucked in 🤩

When I came off Fleet Moss at that speed the main thing that put me off going any faster was the thought that one good bump would have sent me clean over the Armco and down the fellside.

It's the tuck that did it... and a bit of new year's extra mass will always help too..!

As I was thinking of riding fast in France, I just remembered a time I rode more than 50mph on a crappy kids bike... visiting a friend near Beziers, he suggested we go for a bike ride- but with him on his own bicycle (some kind of catalogue MTB, but with a speedometer) the only machine available was his daughter's bike, which had probably originated in an hypermarche some years previously, and was quite forlorn, with its 24" wheels out of true in every direction, shiny cracked knobbly tyres, purely decorative brakes of some kind, and a headset that both rattled alarmingly, and indexed. With the seat post at full extension, I still looked like I was riding a chopper.

Of course, the mountains spoke, and soon enough we were heading downhill fast... faster. Thank god the road was wide and smooth and empty. Physics being what it is, all you have to do is not brake, and I think I remember the bike actually settling down better at high speed. My friend informed me when we got to the bar in the valley that we'd cracked the magic number 🙃 Also did 20 odd miles, I don't think I could straighten my legs for a few days

7-8 years ago I went on a course to improve my hill climbing. When I signed up I hadn't considered this would mean a full day climbing and descending the same bloody hill! We rode this on Hunters Hill, a 1.1 mile climb from 5 - 10%, more correctly known as Bannister Lane. At one point I found myself descending, in full control, at 46mph. I learned three things that day:
  • I can control a bike at 46mph
  • 46 mph is a terrifying speed
  • I never want to descend at 46 again - 32/33 is about my limit

It's quite a few years ago and recorded in one of my many cycling rides diaries. I can't remember the exact speed, recorded at the time on my bike's cycle computer, but I think it was either 54 or 56 mph, so we'll say it was 55mph. It didn't take much effort to reach that speed for just a few seconds as the hill/slope must have the gradient of a ski jump. I got up to about 35 mph then pedaled like billyo at the start of the descent, stopping when gravity took over. I glanced at my computer to see my speed then thought I was taking a risk as nearing the bottom of the hill, there are farm tracks either side where tractors tend to pull out without looking. I braked, dropping from 55mph to around 25mph in a few seconds and that was it.
