I'm still new to kayaking, recently upgraded to a Tahe Marine Midi and going longer distances. I'm not entirely sure how to figure out how much energy I'm putting out but want to learn so I can maximize my time on the water without bonking. I cycle and run so I have a better estimate for what my energy needs are for these activities.
For instance today I did 3 hours on a calm river out and back with a mild head wind after subtracting stop times. I took one energy gel when I was feeling like I needed it. I think I covered about 13 or so miles in this time. I'm wondering how I can calculate an actual reasonable caloric expenditure.
For longer times on the water I'm curious to know what you guys do for energy intake.
