In reply to pink_hippy:
I'm a little late to the party, but I just thought I should add that if the starchiness of the water REALLY bothers you, then you should cook the pasta at home, drain it and rinse it, lay it out flat on a greased oven tray and dry it out in a very low oven (30-40oC), or put it in that nice dehydrator that's been sat lurking in the back of the garage ever since you bought it on a whim a few years ago.
Your pasta, when cooked for the second time, will cook quicker and leak less starch into the water. This is essentially the technique used to make the quick-cook pastas and rices found in many pre-made camping/bivvy meals. I cannot recommend trying it with rice at home, however, particularly if you have a phobia of reheated rice.
Or to avoid the wholly unnecessary faff outlined above you could, as people have mentioned, just eat/drink the pasta water with some packet soup or pesto mixed in, as the starch in the water contains valuable calories and shouldn't be wasted, seeing as you carried them all the way up there.
