Self-confessed short-rider here. That is to say, I'm not short -- I ride (level top tube) a 60 mm frame, c-c; but I ride short distances. When I ordered my Joe Starck road fixie gofast custom (that's 5 qualifiers) I apologetically told Grant that, "Wull, for me, yuh know, 30 miles is a long ride." Grant said, "It is a long ride!" (From that time onward my self-image has been much more positive.) This long before "Just Ride."
Of course, I ride mostly fixed gear on the road, and when I use multiple gears (and freewheels!) it is largely off road, and everyone knows that dirt and fixed add the equivalent of triple the riding distance. Seriously, fixed gears are just perfect for short distance riding.
Typically, I'll fill the working week with 12-15 mile rt errand/detour rides, and once or twice a week I'll get out and ride 20, 25, more rarely 30 miles. But the short rides fit well with my workday -- calls and edits in the morning, writing late afternoon and evening. Today's 13.5-mile rt shopping trip was extended by a very annoying, sealant-splashing nail puncture, though I ramped up the strenuousness on the way home with 4 miles in the hooks against a stiff southerly headwind beating against full rear panniers; 70" gear; I have yet to capitulate and shift to the sissy 63" Dingle gear, let alone the 54" flipside 22 t freewheel.
I am glad to say that I put considerably more miles on my bikes than on my car; tho' this is less impressive than it might be because, apart from my daughter, I drive an average of about 50 miles a month -- much procrastinated, and much hated Big Box Shopping trips (Costco, Target, True Value or Home Depot); occasional drives to church when it's dark or wet and I don't feel like riding; a few social events, though I manage to arrange even some of these at nearby (= walkable) eateries).
