Re the comparison with Audax I did the Rhonndda traverse this year over the Bwlch Rhigos and a few other significant South Wales climbs . My time was recorded accurately by Dai Mountaingoat with a pen at Merthyr Leisure Center and my split timings by the girls in the 2 cafe stops.
Not quite as many riders though
I was also on the Traverse a couple of months back and it was significantly harder than the 120 dragon, which I have my suspicions was a few K short of 120.
Likewise, to be fair to the dragon entrants, you would have thought the organisers of the biggest sportive in UK would have tried and tested all the timing gear rigorously before the event. You would also think that if the cards had been found to be susceptible to damage by any margin of bending, then they should have been mounted on a rigid background.
It looks like the organisers are attempting to provide times if you submit the query sheet, but how accurate this will be is questionable, as there are probably a bunch of guys going through video tapes I type.
I agree, next year there will probably a lot of riders without tags and timed watches, me included.
