As I write this, I'm in a hotel room in Halifax, on the opposite coast from home. In Canada, that's a very long way (4 time zones). The conference started yesterday, and after it finishes on Wednesday, I fly home. It's a total of 7 hours in the air plus another hour-and-a-half to change planes in Calgary. There are no direct flights between Halifax and Vancouver. The important part, though, is that I leave for my bike trip on Saturday evening. I have to work Friday and maybe Thursday, which I had originally intended to take off to get ready, so I might have very little time to organize and pack. At least I got my bike in its case last weekend.

So, what to take? Considerations include the fact that I'll be riding through mountains: I'll have to carry everything I bring up any hills. Also, in the mountains, the weather could do anything. That's the case at home (British Columbia or BC), where it snowed "at higher elevations" last week. Two weeks ago it was record-setting highs. I have no information to tell me that the Pyrenees will be any different. So, layers to suit summer in the mountains.

* These things I'm not certain I will take. It would be nice to have a supportive chair when camping, to sit in while reading, writing this journal, etc. The portable charger can charge my phone or Garmin when outlets aren't available or are located somewhere I don't want to leave those more valuable items. UPDATE I packed both. **UPDATE 2 At the last minute I took out the merino arm and leg warmers.

I'm so terrified I'll forget something! I know most things can be purchased on the road, but it would be annoying to forget something I bought for this trip!

When I get back, I'll comment on whether I would pack the same stuff again for the same trip.
