Used to ride 12 miles each way, five days a week. Switched to a job in London that meant;
11 miles to Oxford,
Bus ride to Hillingdon
6 miles to Greenford
Never got below 2hrs each way. I did this two days per week, until I lent my car to a friend for a medical emergency. Then I did the commute daily for two weeks. Four hours travelling was the issue, not the 34 miles. Occasionally I would ride the 58 miles home. Work commitments meant that this dropped off to driving every day.
Now I live 7 miles from work, but bike route is 15 miles in and 9-11 miles home depending on which route I fancy. I ride fixed wheel to make it a little more interesting, and wave to the planes 😆
