Off-topic, is the skierg any good ?
Not the person you originally asked this of, but I've got one at home, and I'm really a skier first these days, so jumping in here fwiw.
I love it. For background, I'm a nordic skier at heart, which is why I bought it. I think that it is absolutely a helpful training stimulus for classic skiiing, obviously for doublepoling but also for striding to a larger extent than I had anticipated; this probably isn't the aspect you're asking about this for, but if you want to know more about this for skiing, I'll be glad to hold forth at greater length. (I'm a Birkie Elite Wave skier, and medalled at World Masters, if that means anything to you. Not that I'm hot sh*t - lord knows there are scads better skiers out there - but that I'm a decent enough skier at the citizen racer level that I might have helpful anecdata re: using the SkiErg for ski training.)
As for running? I don't know, if you've got the space, and $900, it's a great form of crosstraining. It works your upper body, obviously, although maybe less than you'd think - if you're doing it right (that is, the way you'd do it on snow), you're more dropping with the entire torso than just pulling with your arms, so it might not make your biceps swole right away. (But, well, you're a runner, so you don't need swole biceps, amirite.) It works your lower body, too, maybe more than you'd think - if you're doing it right, you bend at the knees and ankles with each stroke.
It's not easy. I often do 30min as a shakeout workout on days when I have a big foot workout in the evening, that's pretty manageable for me. Sometimes I do 60min straight on it, and I find that a lot of work. And that's speaking as someone who probably spent 300 hours in ski-specific training last year (mostly on snow, but also some rollerskiing and SkiErg time).
Bottom line, as a runner, I'd call it a great low- or no-impact crosstraining tool, but keep in mind that you'd likely have to work up to putting in meaningful amounts of time on it if you don't have a significant nordic ski background.
(P.S. random, but potentially significantly, it doesn't have to plug in; the monitor runs on two D batteries, and the machine itself doesn't need any power source to operate. I have one in the unheated shed in my backyard, since there's really not space for it, or a treadmill, anywhere inside my small house without really disrupting an entire room. The average temperature in Anchorage in January of this year was something like +7° F, with some nights down to at least 10 below, maybe 15 below. The SkiErg seemed unharmed.)
