If you want real friction between groups, have a ride along SDW at weekend. The walkers are armed with poles!
I’ve been riding around Eastbourne end of SDW and Surrey Hills for years, all I’ve experienced is friendly walkers, runners, horse riders and bikers all enjoying the countryside. Use a bit of common sense, go when it’s not too busy, during the week you’ll have these places to yourself almost.
Chill out, slow down when it’s not safe for others, go fast when it is safe for others, smile and say hello.
The place is full of total morons (on all sides to keep things in perspective).
That’s not really keeping perspective is it? Life is too short for bike envy, there’s always going to be someone with a better or more expensive bike than you.
