Moving off the plateau?

Could it be I've moved beyond the 72-73 mile per week plateau? This week's total: 76 miles. This upcoming week is a cut-back week after 3 weeks in the 70s and will culminate with the Boulder Backroads Marathon on Sunday (to be run, not raced). More good news about yesterday's run (besides trying out a new road, beautiful vistas and fun in the snow): I felt great during today's 2 hour run!
