Rucking Cross Training

When I laid out the Base Building Phase that I am currently running, I mentioned that one of my zone 2 cardio activities was going to be a hilly ruck with a 40 pound vest.  Rucking for ultramarathon prep seems to be a topic that elicits very mixed reviews when you search for opinions on it with some saying it has helped them and others saying the time would be better off spent running.  I think it is a bit more nuanced than “it’s great, everyone should do it” or “it’s a waste of time, just run”.  Here is my rationale for using rucking as a cross training activity and why I think it benefits me.

Elevation Gain Differences – While I have access to some decent sized hills, sometimes the races I like to run are often in locations that have steeper elevation profiles than I can run on a day to day basis.  I find rucking up the hills I have access to a great way to build the “mountain legs” required to get myself up those steeper race day climbs.  To me it’s the same principle as using an ultra-training program where they have you perform a prolonged period of dumbbell step ups to strengthen and build endurance in your legs, only less monotonous. While I do think there are advantages to dumbbell step ups and do incorporate them in some training blocks, rucking, for me, is a way to gain a similar benefit while getting to explore someplace interesting.

Not a World Class Runner – One of the common arguments against rucking is xyz champion doesn’t do it.  I think being realistic about where you stand is important though.  A championship runner maybe can run the entirety or at least the majority of their race, but that is not the case for me.  If I’m realistic with myself, I have to admit that there are going to be significant parts of a race where I will probably need to switch from running to power hiking. These parts are significant enough that there is benefit to training the power hiking component as a way of improving my completion time. While it’s hard to say for certain if it has made me a faster runner, it has definitely helped to improve my hiking speed which is a win for my current ability level.

Lower Impact – For me personally, I find it lower impact than running with the added benefit that it uses many of the same muscles as running but in slightly different way.  The slight difference seems to allow me to add in rucking as a cross training session each week without feeling like I am over training.  I don’t run with the added weight as that much too high impact, but stick to a power hike.

Functional Core Strength – Rucking is also a great compliment to other core strengthening exercises and helps you build strength and muscle endurance in your core which helps with maintaining good form in the later stages of race. 

Perhaps if I had everyday access to steep terrain and the time to build up to such a high weekly mileage that running the majority of an ultra was not a question, I would reconsider my approach.  However, as a frequent power hiker without daily access to race-like elevation profiles, rucking is working well for me as a cross training option.
