What is the fastest speed you have cycled ??

[Tim Hall]

The fastest I can remember doing under my own steam, rather than downhill, was the mid 40s km/h on the Graveny Marshes drafting some uber fast person at the end of a FNRttC Whitstable.

The Breakfast Sprint. Makes ordinary mortals, such as you and I, collapse in a heap. I remember @Aperitif dragging me along there at much-too-fast-to-be-healthy-at-that-time-of-the-day mph. At least there's a beer at the end of it.

Very difficult to find somewhere to do that sort of speed, where is it?

The fastest descent in the Peak District is probably Holme Moss towards Holmfirth with a good tailwind. You get a straightish km of about 13%.The fastest timed guy maxed out at 95kmh, a good chunk slower that whoever that was. That's from about 7,000 people's best times. I've managed a relatively modest 90kmh down there and that was a little unnerving

63mph going downhill into Otley back in 2012.

Now it's about 35mph as I have wised-up after a big crash at speed.

 

[SuperHans123]

On my Hybrid, 38.6 MPH down Cefn Bryn in the Gower

 

[Biff600]

8 mph OVER the speed limit of the road I was on.

Not fast compared to some of the speeds on here, but potentially still quick enough to get a tug from Mr Plod and my legs slapped.

Out of interest, on what grounds were you stopped?

That's down Slack Hill near Matlock. Geezer had a van at the bottom waiting to take him back up, took him eleven tries to break the ton.

I wasn't stopped, potentially I could have been though

 

[Johnno260]

On my Hybrid! I am pleasantly surprised.

This was on my steel touring bike with panniers.

 

[glasgowcyclist]

50.9mph on a downhill in Arran a few years back. I foolishly tried to beat a couple of pals and shot past them only to then have to brake very hard for the 90deg left hander coming at me fast. I was never going to make it so had to sit it up, and shot across the road into the grass embankment. Utterly stupid bit of riding which still embarrasses me.

Wow

I've recorded a max of 44.3mph, but my Garmin seems to misbehave at high speeds meaning I'm not entirely sure whether that is true or not.

I'll look back over my ride on Strava afterwards and find that on a fair few of the descents, my speed graph will suddenly have a little spike gaining me an extra 2-3 mph, with a similar sized dip on the graph about 100 yards later (I'm guessing to equalise itself out), before returning to its normal readings again. Quite often this spike happens at a point where the gradient is just tapering out, meaning I end up with a second peak on the graph that's faster than the first, despite the first one being taken at or near the steepest point of the descent.

The fastest I've done on a ride that didn't have one of these "blips" would be 43.8mph, which I've hit twice - once on the descent into Westcott on the A25 during RideLondon; and once down Marston Hill, between Oving and North Marston in Buckinghamshire.
