In order to march across Antarctica on a guided trip, you have to be able to handle the ANI Training Baseline Fitness program. If you’re not able to sustain an hour of intense activity (running, tire towing, cross country skiing) at least 3 months in advance of your trip, you will not make it.
Right before leaving, you have to be doing 8-10 hours a day to have a chance of surviving the ice. Dragging heavy things through really cold places demands massive commitment.
As I look at the training log ANI/ALE puts out, I can see why my last trip to Yellowstone was both good and bad. The good – my training was pretty good. The bad – I wasn’t doing 8 hours a day. Experiencing the consequence of that made me realize a life change was in order. My training was good but not to the 8-10 hour level prior to departure. There’s no general way I can simultaneously work a full time job and train like this.
So, having a little life-altering meltdown may be exactly what is needed to make this whole expedition possible. Dump everything and concentrate on this. Otherwise, all the time, effort, and money will be for naught.
