If you are genuinely interested in a pub crawl from the Lion Brewery to Aldershot stadium, I can give you a list of venues (Standard of England, Ash United FC clubhouse, Greyhound, etc). Up to 1/2 mile between some of the pubs and you could get through roughly 7 or 8 boozers before stumbling up to the ground.
However, if there are a few of you, I would suggest trying to arrange a 'guided tour' of the Hogs Back Brewery (www.hogsback.co.uk). This is a real brewery and well worth doing the tour. Last time I went on it, it was 8 quid a head and I'm sure I had at least 8 quids worth of beer on the way round - they dont scrimp on the ale sampling!!! The place is in Tongham and a short ride from the lion brewery (maybve 1.5 miles). Down the road from there as well is a decent boozer called the White Hart which itself does an excellent range of beers! The White hart has live music on as regular basis and also has regular beer festivals which are well worth a visit!
Around the football ground, your pub options would include the Crimea pub just over the road from the home end of the ground. Probably the busiest pub pre-match if that is what you are looking for. Large beer garden out the front. Under the railway bridge about 100m further along the High Street is a pub called The Beehive. This place has a bit of a reputation for aggro although I doubt many of the wee forehead Burberry capped lot will be looking for trouble on a friendly match day. If you go up Redan Hill (turn left up the hill immediately after the railway bridge), you will find the "La Fontaine" pub at the top of the hill on the roundabout. That is pretty much right where the (quite well hidden) away fans entrance is found. However, I have always found this pub to be pretty dreary and serving poor quality beers by utterly disinterested staff! One street down from there however (on Staff Road), you will find the Royal Staff pub which is unlikely to be hugely busy but does serve probably the best ales in town and is away fan friendly and also has a good beer garden out the back.
Hope that helps.
