Does walking count as cross-training?

If cycling is regarded as cross-training would walking also count? Or are different muscles involved in cycling?

 Would hill work use the same muscles as cycling?

So could hill walking be seen as cross-training? 

with regards to the hill walking, it certainly won't be doing any harm and will increase endurance to a certain extent but for it to be classed as cross traing you need to get your heart rate up to what it woulf be if you were runing

Best you get walking quickly

Walking Rocks!

Hal Higdon incorporates a lot of walking into his training programmes and John (Penguin) Bingham and Galloway are both huge fans of the benefits of walking for running

Walking is biomechanically different from running and cycling  but the big thing is it is low impact so spares your joints a bit /lot

think of it as active recovery

sometimes you even get to the point where you have to choose one over the other ....

I was thinking of long distance walking, especially hilly.

I've walked up and down Snowden and that certainly felt like a good cross-training session.

I was thinking at least 10 miles at a brisk pace. My wife walks but doesn't run. We will do a bit of walking, and - for example - we did a 12 mile charity walk last weekend at a decent pace which included a few hills. It certainly felt like a good work out., and I wondered afterwards if it could be considered cross-training. I usually consider such walking to be recreational, but wondered if there could be plus benefits to walking that would aid my running.
