here's an example of a ride I'm setting up currently. https://goo.gl/EfoFcM .
Its broken in two loops so riders can skip the second loop if they choose. Also, the first loop is longer but with bailout spots so riders can skip the second loop if they want, and possibly just drive to the restrauant to eat. I'll probably have two leads, a fast lead and slow lead to help keep some organization. I've been putting some thought into this ride because its something we will repeat several times per year. Its a mix of road biking and trail, the road bike part is nice, the streets are really wide and traffic slow so its a good place for novices to get some road experience. Its all really flat and not blind corners either.
