Tripswitch-
If by chance you have a Nook, I can lend you my copy of "Primal Blueprint" as I've finished reading it. However, you should be aware that although Mark Sisson has a back ground of marathon/triathalon training, his view is that this is over training and he advises short, intense workouts (weight lifting, sprinting) coupled with a few long walks or hikes or swims but not intense cardio like marathoning. So his book won't advise on how to train for stuff like that, except that he makes a point to say that when he deliberately scaled back on his training that he improved his performance in triathalons. He goes into it a bit. By his standards, I also overtrain since I do P90X.
The hardest part of paleo for me is meals on the go. I think actually it's probably the hardest part for most people. Snacks are easy enough- nuts and stuff are fine- but actual on-the-go meals aren't as easy. That's the part I struggle with.

I actually just downloaded it to my iPad earlier this evening, but haven't gotten a chance to really get into yet... And actually long walks sound a lot more appealing to me right now than training for another marathon...
but seriously, I'm definitely looking forward to getting his perspective... and from what I can gather so far the Cordain and Friel book has info on adapting paleo for endurance training... so I'll have that as a resource...
