Sorry for the late reply, been feeling very low and depressed unsurprisingly.
Thank you for your support and suggestions.
Vorpal, agreed about waterproofs. The coat when new did a terrific job of keeping me dry in all but the worst downpours and perspiration wasn't really a huge issue due to under arm zippers. It's gotten worse over the last year though and yesterday started leaking within the first few raindrops. Useless. Just ordered a can of waterproofing spray
Who knows, it might work
The front panniers are Altura Arran 36's which apart from not being waterproof, have been utterly brilliant since I bought them with the bike 2 1/2 years ago. The problem yesterday (and this is more the racks fault than the panniers) was down to the non horizontal adjustability of the top clips.
The rack was (it was replaced today) a somewhat modified Axiom Journey DLX.
The pannier clips just happened to mount at the ends where the corners of the racks top bar start and that prevented the clips engaging properly. I was hoping the central security clip would make up for that issue. Doh! As if.
The rack originally had little 'pips' welded to the top bar to stop panniers sliding off but unfortunately they were located at precisely the same distance apart as the pannier clips so I chopped them off, drilled some holes and stuck a couple Allen bolts in to do the job. That didn't work because due to the clips not being secure, they bounced loose over the bolts and the panniers started sliding off anyway. You couldn't make it up.
The new rack works though. Tried it today
@ edocaster, rack and panniers as above.
@ bogmyrtle, I can read maps, I can just never figure out where I am on them in unfamiliar areas. Remembering to take the fourth left is only useful if you can remover how many previous lefts you passed, which I never can
which leads me to...
@ axel-Knutt, using the gps to locate position. Good advice, seriously wish I'd thought of that yesterday. Doh!
@ Ben@Forest, it's on my list of books to read. As they say, one mans molehill is another mans mountain. Depression, anxiety attacks and according to my doc, a coping disorder made yesterday's fly in the soup K2 in size for me
@ pal, this tour which I'll be trying again soon (I hope) is only a 215 mile round trip and staying at my dad's halfway and I'm lucky in that I can call on a few family members if I get seriously stuck on the way. Sort of why I chose this route as my first tour really.
Re warm clothing, I was keeping the warm stuff dry so I'd have something to warm up in when I'd dried out a bit. Advice I'd read elsewhere. Not sure if it was good advice though
Anyhoo, new front rack fitted, reverted the garmin to an earlier software version and I think I might have found a map holding bar bag that won't foul the STI levers and hopefully getting that next week.
Round 2 coming up
