Yes, I'm 60 and just did 50km quite easily in 2 hours on an old CX bike. I'm not an athlete, just a fat 60 year old guy.

Long ago I used to ride a small relatively underpowered motorcycle (usually 1960's or 1970s 175cc Jawa) about 70 miles between two cities, typically one return journey a week*. Top speed on the level was maybe 50-55 mph. Large trucks would "illegally" exceed the motorcycles speed. On a number of occasions I tried 'slipstreaming' behind these trucks. The ...

This answer rolls up a couple of comments for completeness, and adds some more recent observations as I've been riding a fair bit in conditions amenable to aero bars - our long straights tend to be on roads that get a lot of fast traffic under normal circumstances. If something obstructs the top of your vision, you'll have to lift your head higher. This ...

I once tried to cycle behind a truck out of sheer exhaustion and curiousness to see what it feels like doing that. It was easy at first since all you had to do was wait downhill for a truck to come by. I had seen other cyclist do it and others even hold onto the back of the truck and get pulled by the truck uphill. So for my case I just wanted the truck to ...

This is an immensely dangerous practice. The kinetic energy of the smallest car is easily capable of killing a human. A truck would be able to instantly kill a cyclist even at a crawl, let alone at higher speeds. Many cycle deaths in London have been due to cyclists being too close trucks. Truck drivers do not always have the best visibility around the truck ...

No,you can get arrested, hurt and disrespected [that is, increasing the level of overall disdain and disrespect that many drivers have for cyclists.] Never try or even think about it.

I say its fine as long as the vehicle in front is not carrying any goods and you're keeping a safe distance/speed. By safe distance & speed I mean the speed you use when going uphill, so that's about < 15km/h and close enough to be able to turn away from it if happens to brake suddenly. About the goods, i see trucks here in Nairobi carrying pipes &...

The energy win is of no discussion. In a lot of situations, it may be even safer to ride behind a big truck or bus. Where I live, car drivers tend to ignore cyclists, but are pretty much aware of the presence of a large truck or bus. The truck/bus driver stands higher and has better headlights so he can deal with the road situations better than a cyclist. ...

This is called "Draughting" or "Drafting" depending on your locale, when done as described. If done on a track it can be motor-pacing or similar. There are even world speed records for bikes that are shielded behind a vehicle. Like anything in cycling, safety is relative. You can choose to ride behind a large solid vehicle, knowing that: This may be ...

It is really dangerous to follow a large vehicle closely. It is possible behind a directeur sportif in a passenger car which is smaller: you can see through it, and the driver is a cyclist who knows you and knows about you. You cannot see what is coming in front of the truck. If they choose to brake hard, watching the brake lights will be of no use; you ...
