I went to High Wycombe for the weekend, left on Friday evening, came back last night...
Did 100 miles each way on just under £15, which I thought was pretty good!!!
I would advise anyone to get free wheeling hubs now, as I fitted some last week!
I was doing 65mph-ish most of the way around the M25 as well

Sorry for the pointless post, I was well impressed, it's the furthest my zook has been in over 18 months
