The average time people in the UK spend commuting each day is 55 mins, with more than 3 million spending two or more hours and 880,000 people spending more than 3 hours each day[0]. In London the average is 74 mins a day[1], and from my experience in London an hour each way is perfectly normal, with 1.5 or 2 hours each way not too unusual, and I've even worked with some people who spend significantly longer than that travelling to work.
