I start my 30 mile a day commute tomorrow. Looking forward to it, getting out on the bike every morning means I arrive at work awake, and the shower in the office means I arrive at my desk clean! I'll be doing about 15 miles from Newbury to Reading, all flat, on 48:17. But may flip over to 48:15 depending on just how flat it turns out to be and how exposed to the wind it is. Just a shame there is no secure bike parking at work :(
good luck mate, you'll love it
