Heathrow Express to Circle Line Connection
I will be staying at LHR but need to get to Victoria by 8:00 a.m. for a day train trip. It looks like the cheapest and most efficient way is to take Heathrow Express to Paddington and connect to the Circle Line to Victoria. How far apart are these lines at Paddington? I'll be traveling about 7:00 a.m. from LHR. I don't want to be running. Is 15 minutes enough to connect at Paddington on a weekday morning?
