YOU GUYS!! I'm so stupidly excited about this!
Did you know that there is such a thing as kayak racing? And you kayak on rivers to get to the next point? I didn't! I was lamenting that I really wanted to get back into triathlon but absolutely hate bike riding with cars and then someone told me of the MR340.
https://mr340.org/340 miles on the Missouri River over two days. I probably should start with something a bit less, but I kinda want to do this just to finish it! Since my elbows are shot, I use a kayak that is pedal powered (Hobie Revolution 13 if you're interested.)
I'd have to train hard to make it. But what an experience!!!
