Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Descending speeds

Just wondering what kind of speeds people have hit descending large hills or even the mountains? What do they get descending the Alps in the Tour? In MPH not KPH please. Has anyone got a speeding ticket? There are huge grades across the bridge from in in Duluth MN miles long I am afraid of looking like this on

I hit 42.3 mph once but I'm a newb. One time I drafted behind a cop car at 25 mph for a short while because the car in front of the cop was staying under the speed limit. I know thats not speed related but I though it was pretty funny.

I've been trying to get speeding tickets for years. Actually I really want to trip photo radar. 42 Mph today on a 6% 2km downhill. Not bad for the prairies.

A speeding ticket would be awesome bragging rights. I think I want one now as well.

My personal fastest is 83 km/h (about 51 mph) coming down out of the Gatineau Hills in Quebec. Scary as hell, and you can imagine how shocked I was when 3 other cyclists went flying past me, probably doing well over 90.

I used to do an organized century ride from Ottawa to Kingston, and there was this one hill with a speed limit of 50 km/h that cyclists could easily hit about 70 on. The provincial police used to park a cruiser at the bottom of the hill to deter cyclists from going all out and flying into the town at the bottom of the hill. I heard that a few cyclists were ticketed the first year the cops were there, but never knew anyone personally who got a ticket.

Why not? Can't do the math.

It's not that big of a deal. I received one bombing a hill into a park area. I was doing 60 km/h in a 40. The cop ripped it up when I ended the conversation with see you in court.

I've hit 50mph on some local short steep hills. Long hills usually have too many switchbacks to let you go really fast.

I think a cop is more likely to give a bicyclist a reckless driving ticket than a speeding ticket.

Like I said it was no big deal. Just a cop being a cop. But that's for the political forum.

i think once you pass 45 mph, you know you are going pretty fast and really have to be aware of everything... i've hit in the low 50's... if you can find several other mates that you trust implicitly on a descent, thats when you can really hit some major top speeds, and perfecting your tuck helps also.

Bikes: 2012 MotorHouse road bike. No. You can't get one.

I've only ever hit 52mph. About a 2-1/4 mile hill, straight as an arrow type thing. One section of about 8% but most at 6% or so.

The guys in the TDF hit 60mph on downhills all the time. Around here, there's a lonnng hill where I can hit 55mph coasting by myself, 70mph+ if I catch a draft on a passing car. At which point, I'm only limited by how fast the car is going and most cars won't go over 70mph on that hill.

I heard Chippolini got one in Italy a few years back... doing 60 mph or something like that.

Bikes: Cannondale Synapse '06, Mongoose titanium road bike '00--my commuter. Yes, Mongoose once made a decent ti road bike.

One time I hit 54 mph on a good downhill. Another time I was going down a slight grade and up ahead I see a motorcycle cop aiming his radar gun at me. As I approached I asked, "How fast?" He yelled out, "35!" In hind sight, I wish I was going 45 so I could have been "awarded" the ticket.

I hit 56 mph once, but that was with a 20 or 30 mph tailwind and a full tuck.

This is my fastest, longest descent. Glacier Lodge out of Big Pine in northern California. ~38mph average down a 7% for 10 miles. For the steeper part I averaged 44mph down 9% for 4 miles. In town, local to me there is a nearly 1 mile straight-shot ~11% descent that I've hit 56 on and excluding the initial acceleration and slowing at the bottom I'll average close to 50mph for it.
