If mountain bike racing in the UK had a spectrum, at the red end you’d have events like the Highland Trail with its duration measured in days. At the violet end would probably be something like downhill, with a duration measured in minutes and fractions of a second.

2. used to classify something in terms of its position on a scale between two extreme points
I’m not usually one for racing at the violet end of the scale; something to do with not enough margin for error, and requiring more emphasis on outright skill than actual fitness. But, I guess it’s good to operate outside of your comfort zone once in a while.
