My local community wants to support cycling events in order to promote bicycling in general and a group is putting together a proposal for a 'cross event next year. After surveying potential sites, we lack any significant "run-up" type features so we'll likely need to build something. I've watched enough videos to see many examples, with and without steps. Are there any documented designs out there for a: mound, set of steps, series of hills, etc. that would help us design a great cyclocross feature for our site? We have been offered heavy equipment if necessary to help make this happen.
