Would love to join you but got a stag doo this weekend.
I do about 25 milies along the path on a regular basis mainly from Bishopbriggs to Clydebank/Bowling and back plus 3.2 miles each way on the road to my house.
Never had any problems, well apart from one ned that was jumping infront of cyclists and playing chicken with them. He was winning till he met me where I sped up lol. Was so funny.
I agree with the start in Glasgow and head towards Edinburgh. The wind tends to go into your face when you head the other way. Well apart from Monday when it decided to turn. If anyone is interested in making this a regular trip let me know. Been doing this for a month or two once a week and reaaly enjoy it. Good way to build up the miles if you are training for a long distances.
