Oxbow/proteus – Guessing you’ve probably never even gone nightriding on your own, never mind tried it without lights, have you?
In good weather conditions it’s very rarely pitch black at night (2 or 3 nights a month tops) and even in the woods the average human eye still can make out singletrack/trail features etc. but then if my guess is right and you’ve never actually tried it I don’t expect you to understand this
Well as the person who originally commented on your claim, I’ve done lots of nightriding on my own, and even some without lights. I’ve also tried it through the woods at a trailcentre accidentally, and IME it gets so dark it’s impossible to see anything at all of the terrain you’re riding over. I carried on for a while trying to do it by feel, as I could just about make out where the trail went through the trees, but gave up before I had an UPD from not seeing a drop-off etc.
I have extremely good eyesight (20/10 vision or better), and more experience of moving through terrain in the dark than almost anybody else on here I’d imagine, with a preference for not using lights until I really have to (I often switch my lights off when running even when it’s properly dark). So I call BS on it being through proper thick trees at a trail centre. My experience of trying to ride without lights has been at CyB and Afan – the most recent on Y Wal, and when I was walking down I was feeling where my feet were going. When I tried to cut down to the main track quicker (because even walking with a bike was quite stressful) I didn’t see the big fallen tree in my way until I was a few metres away. I could ride on the double track when I got there as there was a gap in the trees letting light through.
