Play in the Wetherby League and I don't think we have to travel for more than 50 mins for any match. Nothing that local though, always 20-30 mins.
Same kind of travelling when I played in West Sussex for Ifield. We were based in Crawley, in the north but it was no more than an hour to games on the coast or in the South Downs.
Playing in the Thames Valley/Home Counties League is a different matter entirely - it's not just the distance (Stevenage to Basingstoke for example) but the traffic. Played for Marlow approx 20 miles outside London, travelling into West London to Teddington - no more than 30 miles as the crow flies. We allowed 2 hours and most of us made it in 2 hours 30 mins, one guy took 3 hours 30 mins thanks to a burning car on the M40. The Home Counties League and the feeder leagues of the TVL, Cherwell,Saracens Herts cover a huge area though - bucks,berks,oxon,beds,herts,hampshire, west london.
