Is shoveling snow cross-training?

So, here's my most recent course of "cross-training" events, starting yesterday @ 4:45 p.m.:

4:45 - remove nose from grindstone
5:00 - start drive home @ 40 km/h (25 mph in American)
5:30 - arrive at home - park on street, snow walls too high to get into driveway
5:35 - start shoveling driveway
6:30 - finish shoveling driveway
9:00 - take dog out for nightly constitutional. Realize driveway looks as though it's never seen a shovel. Snow has returned with a vengeance.
10:00 - pull blankets over head, curse snow.
6:15 a.m. - stagger out of bed to shovel driveway
7:15 - finish driveway, so wife can get her snowsurfing VW Jetta out of the driveway
7:50 - kiss wife good bye, make kids lunch for school
7:51 - answer phone call from wife. She's stuck in the snow at the end of the driveway.
7:52 - 8:20 - dig and push car out (with neighbour's help - thanks Jeff!), so wife can surf on down the road to work
8:30 - 8:45 - pack kids up for school. Silently curse snowplow that has turned in at end of street
8:50 - arrive at gridlock, a long way in front of school
8:57 - arrive at front of school. Entries are closed - snowplows have not yet cleared parking lots so cars are not allowed to enter.
8:58 - drop kids with teachers on sidewalk. Head off to work, not thinking about plow.
9:30 - replace nose on grindstone, refusing to think about plow.

So that's nearly three hours of shoveling in two days. This probably explains why my ride tonight was cut short after 45 minutes - nothing left in the tank. That, and the after-work Thursday night hockey game. It's not exactly sport-specific training, but it's aerobic base work. Perhaps it could be best described as "alternate core/stability work" - my back sure feels like it's been through a workout.

And, by the way, I ignored the snowlump at the end of the driveway from the plow. It's just going to have to be lumpy at that end of the driveway until spring.
