Marathon 2011 -alert-alert-alert-

With our group it was that strutting bald cunt.

I'd say "look, we want to do this ride. We hurt nobody, and we inconvenience nobody, so how about just making us official. We will be your official advanced guard to make sure the route is clear and safe. We're not a race, we're a procession, like the Lord Mayor's show."
If they won't countenance it then threaten to do the ride anyway, at race pace, with maximum numbers.

Joke?

Go ahead, get arrested and cause a massive precedent against cyclists on the marathon route for years to come. What's to say that 5 years down the line a small group of fixxie-skidderz couldn't sneak onto the route again when all this has blown over.
