4 and a half hours from 7am would be 11:30. give 30 mins at most for a service station shop. so coaches will be at the ground 3 hours before kick off ?
From the RAC planner Oakwell to Millenium St Total distance: 209 miles (336.4 km ) Total estimated time: 4 hours Don't drive tired. Plan a 15-minute break into your journey for every two hours you'll be on the road. If you feel tired whilst driving stop at a service station for a coffee and take a short nap before continuing. Average speed of 30 Miles/h on national and country roads. Average speed of 60 Miles/h on motorways. so allowing for a stop halfway and traffic I guess 5 hours or maybe a bit more
set off at 7-15 last Saturday stopped for brekky at East Midlands and then again on services at M50 junction for 3/4 hr. arrived at millenium after park and ride for 1-30
