I have never used snowshoes and dont know if I want to start in a 8 hour race.
That said, I have done a few test treks and find moving through deep snow very energy and time draining.
Was this outing in fresh snow or packed because 3 miles at 70 minutes is not bad if the exertion was not high?
were you wearing rubber or steel cleats with the snowshoes?
The "snow" we have is very hard packed, more like ice. I most likely would not have sunk in any if I had just had on shoes. But just walking in snow shoes on firm ground is harder than walking in regular shoes even without the added difficulty that snow provides; I've been doing the same loop almost 15 minutes faster.
Snowshoes are definitely a time/energy saver if you are in deep powdery drifts since any step could post hole you down past your knee.
I had on my icebugs with the short metal studs in the bottoms that I wear for orienteering. I have pretty unsophisticated snowshoes and the place where your shoe goes looked to be pretty hard plastic so I was hoping the studs wouldn't chew it up and that was the case.
Thanks for the info.
Not sure how much the snow will compress by tomorrow but It will be dense. It does seem for the long haul (8hrs) energy savings would be wise.
