So I just hit a big goal I had for this year forst 50 mile ride. Then I did it again yesterday! Heres the weird thing, my average speed is around 14.5-15 on a normal 30-35 mile ride. For some reason on both of these longer rides I maintain an average of almost 15.8mph. Cant seem to figure out why I cant do a higher average on shorter rides. Anybody got any ideas?
