Unless, of course, that the 'Stratford' you refer is is actually Stratford upon Avon, a MAJOR tourist destination / location in the UK, rather than a smallish London suberb?
If this IS the case, travel time (by road) will vary according to the route you choose: the location is just over 100 miles North-west of London and can be access via several different routes / main roads. Typically, from experience the journey in a car will take a couple ours, plus or minus 15 minutes.
