I am looking at attempting my first century this October at the City of Perris California centennial celebration Tour de Perris. It looks to be a fairly flat (2300 ft of elevation gain) My problem is I am not comfortable doing it by myself and cannot find any of my friends to ride with me. How much does human interaction play into the ability to complete? I tend to be an introverted person so it is unlikely I will be "making any friends at the start. Given that this is a supported ride am i over concerning myself? My longest ride so far has been around 50 miles and I still had plenty of fuel left so I have not been too concerned with the distance.
