7kph. If you're enquiring about Q2, they normally plan it so that only the top few clear the kayak course, but you'd need the full time slot quota to do this. Also beware of water flow even if in a still looking canal.
Ok so short kayak then? It just seems like a disadvantage as you kayak twice as far per point :-(
Not analysed that bit. Will probably do that when I see the map.
