due to life schedule, i can only manage around 50-60 miles a week, 2,500 - 3,000 miles a year.

i've never raced or joined a bike club, so i have no buddies to compare with, no experience riding in a group. i've done centuries, but always solo.

i don't necessarily train by how fast i can ride. rather i train based on duration of ride, or target cadence, or heartrate, or power output, or climbing vs. endurance vs. LT intervals etc.

so my question is, what's a reasonable expectation for how fast i should be able to do a 30-mile ride?

i don't need guys who race answering the question, i'm not in your league. but how about the enthusiast riders, guys who ride up to 4-5,000 miles a year? at age 55, how fast should i be able to ride 30ish miles and feel good about myself that i'm a bona fide cyclist?
