It's like Bread had rain on his wedding day yesterday.
Cheers, bud
And Mrs. Gooch, if you want to Go Ruck yourself then more power to ya. While not a rucksack, I use a 2L hydration vest on long runs, and can feel I'm putting out slightly more effort . . . a 10-50lb rucksack would be considerably tougher.
Their claim that X miles rucking (or hiking) is > than X miles running is generally true, at least in my experience. For that matter, walking X miles without a pack is tougher than running X miles. In theory you're burning the same calories, but walking just takes a lot longer and requires more steps.
