Never knew it had a name but yeah, good fun. Think my first SCR was last summer, when I used to be 'too cool' for Lycra (god how thats changed!). I was doing the Portsmouth road from Cobham to Esher (three fairly big hills in a row), when I came across a guy in all the gear, road bike, lycra, SPDs etc.
Was happy cruising behind him until he emptied his nostrils into my path, downwind obviously. Imagine his surprise when the guy on the 10 year old Dawes, wearing baggy shorts and flip flops (Lycra and SPDs are better, I know that now) overtook and left him for dust.
(Anybody from the Kingston Wheelers here?? That's what it said on his arse)
Still take him out now, just give his nostrils a wide birth and a jolly 'Hi' on the way past.
There's only been one guy, who's only popped up on the commute a couple of times who was any match (not that I'm that good, just need more cyclists), and both times I've done 6-7 miles with him, it's hurt the next day.
Although that doesn't count, because he wasn't a commuter, he was practicing on the Olympic route..........
Does the 'lets race because you've emptied your nasal contents at me' genre count?
