Best way to get into it a join a canoe club. They'll have beginner canoes to practice in. It's not as easy as it looks and you need to work your way through the ranks. Then you can get into whitewater races like Dusi,Fish etc.Agreed, I doubt I would be able to run continuously for more than 10km.
I do like the row machine in the gym, I see some people do canoeing here by the lake (tygervalley), I always look at them and think, that looks cute, but no idea how to get into it, like where do you even buy one and who do I ask to go canoe on the lake.
Where do you canoe?
No use buying a beginner boat as you'll only paddle it for about 5 months or so, and then move onto an intermediate boat. I mostly paddle on the ocean in a surfski.
