As the op notes, I was one of the riders who saw rider #36 at the tower after the event. Whilst part of me thought this would be great fun, I agree with udder on this one. Ok so 36 riders this time with no issues, but what happens when 50 or 100 turn up? As mentioned above, there is a lot of sensitivity about biking in the area, and it’s far too easy to latch onto this type of event and create negative stories.
Keep it underground, don’t do it in the same place twice and I don’t have too much of a problem with it, but to make this a regular thing just invites trouble.
