I was (am still) having trouble getting the right blade depth - Roger from the Edon importers suggested straightening my legs before pulling with my arms. This was a very helpful piece of advice and I'm trying to implement it now. Sometimes I forget.. I've also put a little clip of clambering in and getting away from the dock as there were some questions about how to do this on one of the forums. Hope it's helpful. Now had 8hrs and done 23.5 miles - that's an astounding average of 2.9 mph. Hmm - not quite Olympic standard yet.
