Does anyone else think the BBC article has a nasty undertone suggesting the newcomers are better than the evil old cyclists they've been complaining about for years? Like not having cycled lately is a good thing: "After doing next to no exercise for two decades, I bought a road bike in 2012", "I didn't own an adult bike until was 28", "took up cycling when he was 51", "bought his first road bike when he was 40"...
And finally, if anyone is obsessed with times and constant improvement and other BS, either you'll get over that when you hit your peak, or you'll become depressed at your descent into illness and/or old age... I suggest getting over it is more beneficial
