Things I have also learnt over this tour is Wiggins is a crap presenter and generally gets on my wick
He's good for some anecdotes and 'inside the peloton' type stuff but I don't really rate him as a presenter. Like you - I found he gets annoying very quickly!
I was pleasantly surprised on how good the ITV coverage was and the presenting has been great, Ned Boulting has been great this year and David Millar is always fantastic. They work well together. Not sure I'm a huge fan of Chris Boardman, but he's not as annoying as Sean Kelly and some quite good out-segments with him discussing other things 'cycling' which have been great I guess rather than just complete coverage and nothing else. Some 'dumbed down' bits about modern bike tech for the masses. Pete Kennaugh has been good, Gary Imlach is pretty much second to non for a highlight show. The only 1 of them I don't overly like is Mat Rendell (older guy, he's a bit dithery) but mostly as he comes across as more of a journalist and slimey at times, than a commentator (which he is). Still some good bits and off-hand comments/questions kinda prove why he's there.
Then because ITV with their catchup app had full coverage as well as the Highlights meant I could dip in and out of some of the best stages when I had the time to watch more than an hour. So I didn't feel the need to go for the GCN sub. Shame the ITV team don't do the whole Pro calendar really, as it'll only be a matter of time until Sean Kelly sends me bonkers in the Classics. I give it maybe 45 minutes of the first race.
