You're probably right. At the moment it is just as quick to walk with the bike. Any segregated path would have to be the other side of the fence (on the other side to the railway) which is probably owned by the Uni.
I consider myself something of an expert on this, having cycled to most games staged at the Amex and many other grounds as well - all to follow Albion.
Our facilities are very good. If there was more uptake, I'm sure more cycle stands would be provided. I think a cycle lane (segregated) is...
