I don't doubt for a moment that many have broken alloy frames in the past, I would like to emphasize that in my posts I have used statements like "and from the major manufacturers" and "modern" to try and illustrate that over the past few years bikes in alloy from the well know manufacturers have proved reliable and even more so than when the market leaders of their time used mainly steel.
To an extent in the early years, especially the unbranded variety that are all to common place, many alloy frames did indeed break at such a high rate it was not acceptable, fortunately I have had the luxury of never having to work in retailers that stock these quality of products. My advice is to buy from a recognised manufacturer as even their budget bikes have had an extensive amount of R & D and it shows. Of course alloy frames have also now been around long enough for many of the earlier problems to have been ironed out.
I completely agree with 'OGlover', the Trek Pilot is indeed a much tighter clearance machine and only really suitable for light touring and fast day rides, Audax for example, the Dawes Audax range being a much nearer comparison, I had mentioned them to illustrate a point I was making about the Trek and Specialized touring and Audax bikes in general as apposed to suggesting them as an alternative to the heavier load carrying capacity capabilities of either the Galaxy or Specialized TriCross.
In conclusion you need to look at what you want out of the bike, an Audax bike can to an extent take quite heavy loads
As you can see I have done just that above and have done two week tours just like that (although not Lejog I have to say, that was a supported tour so I was just gettibg to Lands end

) , but it is all a bit Russian Roulette, with heavier weight the bike is less manouverable for last moment pot hole avoidance for example, the thinner section tyres and rims result in a more delicate wheel so you do have to take more care as a result. The more specific Touring bikes will also be more stable under load, although I personally get use to the feel of a fully loaded Audax bike.

Well, my friend and I have both had cracked aluminium alloy frames, so I can only speak from experience; perhaps we were both very unlucky.

Bear in mind that Trek Pilot clearances are still relatively tight and if you are tall (and presumably have large feet) you will get front toe overlap with the wheel and that’s without mudguards. Not insurmountable and I have ridden bikes with this situation, but why bother when you can get a bike that will definitely meet all your needs including the heavier panniers? Also, don’t forget you need a bike that is designed to carry weight that includes consideration of the wheels, which I don’t believe the Trek Pilot is really designed for – great bike for say Audax, but for touring with panniers I believe there are better bikes available.
