Jethro has just been in contact with me off-board ... the ride first took place in November 2004 when we are all at Cycling Plus .... IIRC there were about 20 riders, including a number (myself included, Naggers and Charlotte, and Basil for part of the ride - I think Jaded showed up at one of the reruns) that still lurk here.
As suggested, I would be surprised if Russ was up for organising it again in the near future ... BUT I, as a four time veteran of Ru88ell's Legendary Tunnels Ride would be willing to step into the breach and run it, perhaps in April or May?
May I suggest that if you are interested you post a quick reply in this thread with any suggestions on dates ... if there seems to be a quorum I'll start another thread with a firm date and details.
UPDATE : I've just added a pdf of the map to my website - it's in Rides/2004-5 under the piece about the Tunnels ride - link should be

Oh, don't forget "Skinny's Leap" [you had to be there - past member Skinny leaping off a bank near the lunchtime pub and departing the throng in an ambulance with a broken collarbone] .... and I'll check with Russ that he's happy with the idea.
AND if you've been before I can't promise the full two-way radio caboodle ... although I'll ask Russ if I can borrow his clipboard
