Altitude training - anyone with experience?
I'm doing a high altitude ultra this Nov and I'm aware there are various at-home solutions for acclimatisation as well as labs where you can train at simulated altitude but need a bit of a steer. There's a number of other runners and mountain type folk on here and I was wondering if anyone had any first-hand experience of any of these as this is something new for me (part of the appeal); or if any were more/less effective than others? The logical place to ask would be an ultra running forum, but I seem to spend more of my time on here!
TIA
