Screwed

If I don't run a marathon in Fredericton in a month, I won't have another local marathon opportunity til wayyyyyy later. I don't see how I can be ready in a month. But if I drop to a half, everything I've done is for nothing? I'm so screwed. :(
ETA I suppose I could aim for the Nova Scotia Marathon at the end of July. Because nothing says hard core like a mid summer marathon SIGH
