What's the longest feasible commute? My current run in to work is 10.2 miles door to door. I do that between three and five times a week, giving me between 61 and 102 miles a week. We're moving outside the M25 in a couple of weeks, and although I've not done the run yet, Google Maps says 22 miles door to door, or 44 miles per day. Five days a week, that would of course be 220 miles a week, which I guess some of you probably do. For context: 52 years old, big bloke but moobs and a slight paunch are part of my world. Legs are strong enough, and lungs can cope with the current commute without any problems. Would it be a case of building up to it, or maybe do half of the journey by train? Are there any of you who do that many miles?
