Thanks for the comments about future ride safety. I think for the time being we'll just monitor the situation on the day depending on the route and numbers involved, and then brief accordingly. As to an extra, speedier group (the Chasers) I suggest we can hang fire on that for a little while too. Although one or two riders were slightly stretched at yesterday's pace, everyone managed to cling on. As long as we keep an eye on the back markers and re-group at obvious locations (T-junctions, route changes etc) we should be Ok. Terry did a great job yesterday of looking after the back of the group, which certainly helped me to make sure we followed the route and chase down the friskier element on the front.
