COnsidering one job and it would mean travelling London to Ascot ( through) Windsor. The google map shows 24 miles 37 min. The job is a promotion for me, but just 2,000 more than I have ( I commute 8 miles at the moment). Not sure whether I can estimate time how long it would take form london to Ascot - I need to be there for 8.00 am in the morning.
