Sometimes goals can work against you. Ride how you feel on the day, what you feel you need to. If thats long distance...good. If its short distance...good.
I'm struggling to get fitness back and using goals to push me, but when i was fit, 50 miles was normal, anything less was warm up, i think 82 miles was my best and it was always done hard.
BUT...i did get to the point i started to bawlk at the idea of big mileage, i started mythering pre ride, thinking about the several hours out there, which i loved...but it was just the amount of time i'd spend doing it.
My goals were always faster and longer, it drove me on un til i could do 50 miles at 18mph average, not immensly fast, but i hardly ever ever got overtaken. Then i started getting tired of pushing so hard., so i backed off again.
Ride how your head tells you to. Whatever works...works.
