riding in a group in oxford

Unless it's race you wont have to.

Of course if your organising some sort of public event you might choose to do so as part of your risk assessment etc.

It is no different to organising a walk with 10-15 people or a car drive for that matter.

Booga and Dan, thanks so much for your insights. i guess you're right, its just like having a group of friends walking or driving together. its just a fun ride among friends, nothing near to a racing event. this is such a friendly forum, thanks so much for welcoming me! great people
