i'm usually somewhere between 13-15mph. i am aiming to try and get this to about 18mph average this summer, anyone got any good training tips to help increase the speed?
So far i have a 16mile route that i time myself on. I dont own a bike computer, but use this site to track my progess.
www.mycycling.net (it's pretty good)

I'm thinking if i just push harder, get stronger and more stamina, the average speed will eventually go up can't wait until it does!

I look up to those of you averaging around 18, well done!
