I am not a sports psychologist, but I have spent twenty years watching athletes either grit through hard days or quit on them, and the difference is almost never fitness.

Rucking past about 6 miles (10 km), and especially past 10 miles (16 km), is more a mental event than a physical one. The legs will keep going long after the head decides they cannot. Here is the toolkit I teach. Decide what success looks like before you start The first thing I tell every athlete heading into a long event is: define success before you leave the house. Not at mile 8 when the wheels are coming off. Now, sitting in your kitchen, when you are calm. Is success finishing? Is it finishing under a certain time? Is it finishing without sitting down? Is it just showing up to the start line after a hard training block? This sounds soft. It is the single most useful thing you can do. Here is why: when the hard moments come (and on any long ruck they always come), your brain will start negotiating. "I could just stop here." "I have already done enough." "Nobody would blame me if I cut it short." If you have not pre-decided what success looks like, every one of those bargains sounds reasonable. If you have, every one of them runs straight into the wall of "no, that is not what I came here for." The negotiation ends. You take the next step. Most success in endurance work is not talent or fitness. It is knowing why you are out there and refusing to let your in-the-moment…
