Could you tell if during that part of your trip if you had a headwind or a tailwind?I could not say exactly how strong winds were, but I'm guessing around 50-60 km/h winds (32-38 mph) probably more than that. Canoe held ok afterall. Just before mid-trip, I realized we just did 100 km (63 miles) and actually consumed 200 km (125 miles). My consumption was around 240 wh/km (384 wh/Mi).
Even without any wind, the canoe is going to add a large amount of extra drag which will significantly increase energy usage.
That low consumption figure was likely due to a large tailwind.on our way back home, when I was on road, direction south, I had a consumption of 170 wh/km (272 wh/mi). So I though to myself, hey, this isn't bad after all. It was just a very windy day for both our way to camp site and to home. That was until I turned west. Consumption went back to 240-250 wh/km (384-400 wh/mi).
