I have the 20L, not 25L. I think the confusion is because
the post where I specified the 20L I included a link to the product page set to 25L. But it's the same product page. You pick the size from a single page and I wasn't paying attention to that when I generated the link. I'm 6'2" which overlaps the height recommendations for both sizes, plus I'm somewhat broad, but the 20L fits me fine.
I'm still going strong, averaging about 8-10 miles a week and I just passed 360 miles for the year. Looks like I'll finish above 400 miles for 2025. I had a fair bit of
life interruptus this year and next year looks to be the same. I'm going to target 500 miles for 2026 and see how that goes. Summer was pretty hard to maintain. I often found myself doing shorter sessions. I also needed a day off after a strong effort. I try to do it 3-5 days a week, but in summer I rarely did more than 3, and occasionally just 2. I could lift or do indoor cardio the day after a hard ruck but consecutive rucking days was tough. The last month I have been picking up both distance and frequency.
Most days I carry 30 lbs. I occasionally drop to 20 and more rarely go up to 40. I have 50 lbs of plates and might try that once soon just for the hey of it. Finally, I work hard to maintain a regular sub 16 minute mile pace. That's a reasonably quick walking pace. As a reference point, I understand a sub 15 minute pace is military standard for 8-12 mile rucks with 40-55 pounds. Being 63, I'm happy with my 15-16 minute pace, 30 lbs, and 2-4 mile standard session.
