Peaceful commute in this morning

Loads of fog around though, so perhaps my friend on the motorbike couldn't see me today.
No joy with increasing the audio channels, I've tried with avidemux, but the wind is too loud. I'm going to try moving the Virb over to the right hand side of my handle bars, nearer to traffic, to see if that helps. Failing that, I'll buy an external mic, and only use it in the dry.
Just been reading back through the thread, as I've not been online much lately.
Love FrenchTart's new bike, you've seriously got me tempted to build my own now. Carbon with hydraulic discs must be amazing!
I'm struggling a bit with trying to increase my weekly mileage. I can get to around 150 miles a week (my goals is 250-300 miles a week), but then I find the following week, I can't do nearly as much. I don't feel generally fatigued, but my legs feel heavy most of the time to be honest. I think my problem is a combination of nutrition, and going too hard all of the time. I've increased my food intake drastically over the past 3 months, and yet I've lost even more weight. I'm down to 9.4st now, I was 9.8st at the beginning of this year!
I think I'm going to get another bike fit done, just incase it's position related. I had a Retul fitting done in May last year, but I'm starting to wonder if the fitter actually did a decent job. He didn't even look at my cleat positions.
Also, what do you guys think about bringing a backpack, and using trainers on a group ride? I did this on Sunday, and the group I was riding with politely asked me not ride with them unless I had clipless pedals, and no backpack. I thought they were joking at first, but apparently not. I only took a backpack as my jersey had no pockets, and I hate saddle bags. As for the trainers, my road bike is out of action, so I used my commuter bike which I don't like having clipless pedals on (too many stops).
Would you guys care if I dressed like that on a group ride? Does it really matter that much? I'll still beat most of them up the hills
