Anyone doing London - Brighton Night Ride?

[Type R Tom]

Will be doing my first long organised ride this weekend, the London to Brighton Night Ride in preparation for the Ride London in a few weeks. I'm slightly apprehensive having never ridden in groups much before but I'm confidence I can do the distance (with a few gels). There are 4 of us and the others are pretty fit, hope I don't slow them down.

Anyone else doing / done it?
