Smollet, I'm intrigued by your Sunday AM paddles of 36 miles, and your all-day trips of 72 miles. In how many hours do you complete the 36 and the 72 mile outings? And what sort of boat & paddle are you using? How often do you make these journeys? Are we talking statute miles or sea (nautical) miles?
Statute miles. 36 miles typically takes me around 8 hrs. Thats just a little over 4mph, so its no speed record there. I do that about once every 4-5 weeks as part of my endurance training.
I will do a 12-20 mile paddle twice every week for more intense training. An all day trip is early AM till dark, depending on what time of year can be 16 hrs. It's not hard to cover some huge distances especially on rivers.
I use a QCC 700x
