I've been asked about leading rides. I'm happy to do this, but also if someone else leads. About half the time I'm cycling being part of the ride is attractive, leading or not isn't important to me.
I have various rides I have mapped out and ridden, typically 40-50 miles based around Upminster, Crews Hill, Amersham/Chesham/Chorleywood. Some of them are based on CTC rides, either partially or a lot. I usually visit north and east of London, so Essex, Herts, Bucks.
I like a 2 ½ * ride, a fast Blue Oyster Thursday. There are often a few miles of compact earth, similar to Nick, Felix, Richard D.
Thursdays are best for me, but I can occasionally do Sundays and Mondays too. It's possible I can step in at short notice sometimes.
