It will come back faster than you think. The first few rides will probably be a little more difficult than you remember but I would honestly be surprised if you are unable to finish your loops. Don't worry about it, rest up and get back in the saddle when you are ready. No need to rush and hurt yourself.
You know, now would be a good time for you to do some maintenance on your bike. Check your brake pads, tear down and clean the drive train, lube cables, check your tires pull out the bits of glass and wire, hand wash and wax your frame. That way your bike will look just as shiny as the day you brought her home when you're ready to roll again!
