I've always eaten far too much bread as it's just such an easy option for breakfast, lunch and snacks. I hardly ever touch it now. I have noticed a definite reduction in airborne toxic events when I'm not eating it too.
Absolute pure paleo has no dairy in it JBit, but I have foregone that as I don't personally have any issues with it and would find the extra restriction a bit of a hassle. As my aim was just to eat more natural food and less carbs, then milk, natural yoghurt, cheese (in moderation) and butter seem to fit in to that diet quite well. I'm sure some paleo purists wouldn't consider my diet paleo at all, but that was my starting point and I have made little adaptations as I've gone along. For me, it's losing the bread and sugar that have made the difference.
That's a great idea booktrunk. Have just looked at Cotswold Way century (I live pretty much on the Cotswold Way) and they're after volunteers and you get free entry the following year (which scares the crap out of me) so might give that a go. I do have a HM the next day though and am mega busy at home at the moment too so possibly not the best timing. Will consider.
Scott Jurek had a thing in his book about switching his breathing to being only through his nose and reckoned it helped him a lot. Not sure why.
Anyway, my nasal passages are rubbish (always congested, have to use a nasal inhaler regularly) so have to breathe through my mouth when running, although have had small amount of success with nasal strips in the past. I definitely see improvement when I concentrate on deeper breathing but my concentration levels are almost nonexistent so it doesn't last long.
I've just started Hal Koerner's Field guide to Ultra Marathons, which so far has been a good read. I'm yet to dip my toe in the Ultra Marathon waters, but I'm very keen to do so. Am just waiting until I have enough time to properly dedicate to training. I will definitely do one next year at some point. For now, I can just read about them!
