Well done Davie. I think I know roughly wear you are. What was traffic like on the A8 Edinburgh Road ? it can be very busy at the eastern end (A8 Glasgow Road). I think I've cycled Gartloch Road once before I can't really recall much but I don't think it was busy.
I done my 9 miles in under 35 minutes today. Im going to do 10 mile across the town tomorrow and back (with a cup of tea in between. If this goes ok im going to increase my daily cycle to 14 miles I made another route with google maps, undecided if this is too much too soon and I dont know what the inclines are like on new bit. For anyone that knows the area Ill post the new and old.
