I commuted from Hillingdon to Acton, west London. Great! No hills.
My commute for several years was from Castle Bromwich, east Birmingham to RAF Higham ( M.I.R.A. ). That was up and over to Atherstone 17.5 miles e/w.
My strangest commute was to ride to Water Orton railway stn to get there at 05:57. Get on a train for 10 minutes to get off at Wilnecote on the A5. Ride to M42 J10 Tamworth services and stay there watching the morning news for 45 minutes. Then ride along the A5 to M.I.R.A. to get there at 07:50. Most mornings, the guard waived the fare for just one stop. He couldn’t be bothered walking along the train to me.
Before this, I commuted from Castle Bromwich to Hockley, west Birmingham; and back with the slow moving motorcars under Spaghetti junction.
The secret with commuting is to allow plenty of time, ride steadily and observe what’s happening. Sometimes its comical being overtaken by a youngster on an old MTB deliberately trying to ‘scalp’ me.
