what's typical?

fast day on the 4 mile commute - 18 mph, including wait for lights.
last solo century - 15.5 mph

once I let my average go for a year and got 12.5 mph - soooo slow.

I haven't raced in forever, but I do remember an average from a 62 mile race came out to 28mph and I finished in the second group, maybe 10 mins off the lead, IIRC. Point to point road race, all cats. Almost completely flat. There was one 200ft bump to climb over. A couple of nasty wind sections, but not bad.
