How long should a 20 mile bike ride take? It took me 1 hr 15min and there were 3 hills (2 small ones and one probably not what any experienced rider would complain about but for me i went up it going 5.5 mph). This is my second week riding and i have made it the past 2 days going 20 miles back roads with little hills and one that really hurts. My bikes says i am averaging 14.7 mph. I am just trying to see if i need to speed it up i would like join a bike group but want to be sure i can keep up first. Thanks
