I gave myself a rest day then found a nice steep 300 vertical foot hill on the outside of town and went up and down, up and down. Tomorrow I'm going back with weights in my pack. Flat land training, whether running, skiing, speed walking etc. just dosn't cut it in the NE.
I used to live right near a 200-300 foot hill. (But then I had to move and ended up in the flatlands.
) I would put up to a 45lb pack on my back and walk up and down the hill. Enough exercise to build/maintain a reasonable amount of fitness, not enough to exhaust or hurt myself.
To stay in shape, going out only on weekends isn't enough (even when I was younger
). Walking the hill once or twice during the week made a big difference.
As for thermal managment, a good goal in winter (below treeline) is to drop enough insulation so that you stay just slightly cool*. This prevents water and energy loss due to sweating. (Also keeps your clothing dry.) Different people can produce widely different amounts of heat, so you have to learn for yourself how much insulation is required. (And it is ok to stop occasionally to add/remove a layer if you become hot or cold.) The problem in winter is often dumping heat rather than keeping warm. For example, I am frequently stripped down to my bottom layer of the thinnest available moisture-wicking polyester tee shirt** while a partner still has on a wool shirt and shell.
I have seen people wearing expedition down parkas with sweat streaming off their faces at temps around 20-30F, but they keep that down parka zipped all the way up. (After all, its cold out...) Idiots. I have also helped rescue some of them.
* Above timberline, the goal is to stay just slightly warm because of the potentially higher winds. And if it is windy, lowering a shell zipper just an inch or so can dump quite a bit of excess heat.
** The reason for using a very thin first layer is so that you can strip down to it to dump a maximum amount of heat. Removable insulating layers and shells go on top.
