Yes, but it’s faster, cheaper, and more flexible, the travel time is consistent and it’s more fun on a bike commuting in and out of the central london, even when piss wet through tbh: I have a locker and shower facilities which helps.
Obviously i have a number of other options for 65 miles each way (3 times a week) combining the use of cars, trains, tube, Brompton in various ways, but public transport as well as being expensive (with no seat guaranteed) is a drain on the soul done regularly; so I use sparingly on a needs must basis and everytime I wish I didn’t have to. If the weather is really bad I’ll work from home..
