its not a race as I “politely” reminded the grumpy old roadie who barked orders at me about ‘holding the line’…
This.
Call it what you will, but lots of people will be riding as hard as they can in order to post a good time, so it’s often hard to distinguish from an actual ‘race’. In fact this is why I enter (and enjoy) sportives, it is the only way I get motivated enough to ride at 100%, if I’m just out with mates I find it hard to bury myself the way I would in a sportive.
Having said that, there’s no obligation to get trapped in the roadie club/group mentality, just let them get on with it and do your own thing, or ride in a smaller group, or solo.
I remember spending a good portion of my first Bealach Mor Sportive chasing a distant figure further down the road. When I (eventually 😳 ) reeled him in and paused for a chat, I realised he was at least 60 and riding a £350 Ridgeback Velocity hybrid, so yeah, any bike goes.
