Greetings. I'm casting about, trying to get ideas for next summer's tour(s). The John Wayne/Iron Horse Trail in Washington State sounds intriguing.

I would be touring on a Surly LHT with racks and panniers. Would I be able to do this trail? I have Schwalbe 32s on it. I could go with something a little wider if it were called for by the trail surface. Any advice?

I also have an old Specialized Stumpjumper (no suspension). I could take this, although it's not as comfortable. The handlebars are much lower than the saddle. I suppose I could find a taller stem and change this.

What dates would be best? I'm a teacher so my window would be from mid-June to mid-August

Any advice?

Thanks!
