What is the fastest speed you have cycled ??

[User10119]

40-something-I-can't-remember, on one of the rolling bits on the Dun Run in 2010. Because I was on the back of a (sturdy and somewhat well-loaded with panniers, my really rather hefty self stoking and a pilot who outweighed me, just) tandem with no access to the brakes and therefore had no control over descending speeds....

A fairly pity full 35 mph. The hills around here are lumpy rather than long, so I usually run out of hill before I can reach a respectable speed. Going to have to visit somewhere with some proper long descents.

If my cycle computer is correct according to the maximum speed reading I reached 52 mph descending Mont Ventoux.

My fastest down hill is 49.4mph down Fish Hill, in the cotswolds. I do have a randon set of 4 rides where i broke the 1500mph barrier, but i'm sure thats not correct.

As for speed on the flat, I can manage a constant of at least 36mph on the sprint home into my village. There is a hump bridge about 2 miles out and the road is just very so slightly down, you can't tell if you walk the pavement but it just gives a great advantage over the two miles, and the prevailing SW wind does nothing but help more.

49.8mph. Loaded touring somewhere in Colorado. On the Transam

Around 38mph, according to the 'you're exceeding 30mph by this much' sign on the run into Brighton on last year's BHF London to Brighton. Scared the bejeepers out of me, but when bike and rider weigh that much, physics takes over!

Let me guess: the 12% downward grade section going down to Malaucene? I reached 51.5mph on that bit.

Can get that going down the nearby main road, freewheeling. We've a few long un's you could try!

48 (point something) on a very long steep road section.

Not bad on a GT Avalanche.

Couldn't possibly go any faster as my legs were spinning out - even with a 48t big-ring

You are probably right. It was somewhere on that descent.

45 mph only last night. Bayworth lane from Boars Hill just south of Oxford.

52 mph on the A470 after the climb out of Blaenau in Snowdonia. Good surface wide straight bit of road with no side roads to worry about. The KOM on Strava hit 74mph on it.

Good bit of road that. Hard in the car.

Call me cynical but I never trust KOMs when they claim it was with a "sidewind". You would have to be sodding crazy to go 70mph with a sidewind.

The climb after Blaenau to get there on a hot day is pretty unpleasant.
