Depends on the roads. I couldn't do it on congested London awfulness, but if it was free flowing I'd love the mileage. Look forward to it, even.
I do look forward to it, when I'm not knackered. But it includes about 10 miles of steady climbing, never getting above 3%. So looks flat, but means when I'm tired it's harder to get the bike rolling and seems to sap energy. I end up too tired to cycle more than two days in a row.
Still, it beats the train any day!
