So the Euros have U23 competitions at their xc and track champs and FIBA and FIFA also offer similar competitions, I think cycling might, too. So why doesn't the US or North America (PanAm or NACAC) offer U23 races at their championships? It would be a nice way to encourage good college runners to maintain continuity after college, rather than quitting for a few years (or forever) before getting back into it. It doesn't have to be U23, either, it could be U24 or U25.
