Not sure if this qualifies as it isn't an "arena" in the modern sense.... I couldn't think of anything else here that would be an arena not featuring balls/bats, perhaps the biggest would be the Manchester Velodrome. Most non ball grounds - athletics/cycleing here have closed/moved to the huge UCLAN sports complex and is more of a campus than an actual arena...
This is at Fishwick BMX track (a national race track) off London Road, Preston. I was going to attempt a crowd pleasing backward 360 off the table top but alas I couldn't get the bike through that gate there....

The club used to be at Deepdale where my brother and I would take our BMX's, it was bulldozed to make way for a Sainsburys before reopening here in 2005 or so. It is itself built on the old running track.
