Recentley moved back to kent after spending 6 months on the coast in brighton. Now have an 11 mile commute to work, which I am to tight to use the car for. In the past, last year I used a road bike but now only have access to a Hybrid a giant Crs. My question is this with my road bike I could get the journey down to just under an hour as there are a lot of hills with my giant Crs its taking over an hour where am I going wrong.....I know that my average speed has dropped but surley it wouldnt make that much of a difference.
