I shall be joining the 17-30 train from Paddington at Didcot. Doesn't get to Bristol temple meads until 19-15, so my pub of choice will be the First Great Western buffet car.
Cheers. Have looked at Parson Street but trains are too irregular to get last train back towards London unless I leave with 10 mins to go. Google maps says just over 2 miles from BTM to ground; I'll wear my running shoes.
