I've been commuting to work every day and popping out for the occasional lunchtime razz for about four months now and I'm starting to get fast (for a fatty). An average clear cruising speed is around 24mph and I can hit 37mph on a good hill (of which there are few in these parts).
But I've now read about so many horrible accidents and seen enough terrifying helmet cam vids that I'm seriously considering deliberately riding a lot slower.
Speed has always been a big motivating factor in my cycling, so I feel a bit sad about not giving it my all, but I've had a fast face-shredding head injury in the past and don't want another.
Any thoughts? Am I missing something obvious here?
If as a self-confessed 'fatty' you're getting a cruising average of 24mph, you are doing very well after only a few months. I used to commute a (fairly lumpy) 21 miles to work a few times a week and thought a 21mph average was excellent - and I was in good shape at the time.
As to speed... I don't see speed itself as a danger. Spinning along rural roads in the mid-20s is of itself not dangerous. Danger may come from fauna rushing into your path, other road users or detritus on the carriageway, but none of those is a function of velocity.
Descending at anything at or over 37-38 is where it starts to feel 'fast', but I'm not sure it's much more dangerous than doing so at 30 and not much safer than doing so at 45. Having said that, there are descents where I ask my younger kids to stay under 20 or under 25 for the time being. Not all descents, but one or two.
In towns and cities, I regulate my speed quite a lot. There are places where I could absolutely hammer it, but do not. This is much the same as the way most people drive cars. The speed limit is a limit, not a target speed.
Do ride more slowly if you want to, but those camera-footage incidents are a lot rarer than you might imagine.
I'm guessing that you might be around forty years old. I recall that caution entered my thinking at that age in a way that it had not previously.
However, experience is a great friend. Everything that's ever happened to you on a bicycle is stored in the hard drive of your noggin. I'd counsel you not to have your thinking informed by YouTube bloodfests, but by what experience has shown you to be capable of doing safely.
What you may find yourself doing is taking everything down to a lower speed and then gradually putting that speed back on as it feels right to do so.
In conclusion:
1. Speed of itself is not dangerous - the location and the surrounding road users may make it so.
2. Cycling is meant to be enjoyable, so ride at the speed you enjoy. Bollocks to speed, it's just a number.
3. Do not feel the need to see slowing down as a permanent thing. If you feel like it, you'll find yourself speeding up again.
