London fan here who attended the game on Sunday. It was 546 mile round trip. We set out at 8am and got home just after 11pm, having made a couple of stops each way.
It was quite entertaining speaking to a lady in the bar prior to the game who complained it had taken here half an hour to get to the game.
I live in Kent, it takes me ninety minutes on a good day, to get to a home game. I would say that the majority of London fans travel at least an hour to attend home games.
I am not complaining, just pointing out following the Broncos home and away takes commitment. I am fortunate to be able to to do so.
Widnes in a couple of weeks another 500 plus miles. But then following the Broncos is what I do on a Sunday.
