These are good points, but I can assure you that there are race plans and so on considering all this... not that I'll reveal them, though, you never know who might be reading this

To be fair, race pace for the first minute or so will probably be high at 38+. It's just the adrenaline, I suppose, and I will be riding on them to keep efficiency, and will doubtlessly drop down.
In terms of fitness, though, whilst they aren't the fittest boat on the river, 2k at rate 36 is achievable. We managed all of Head of the Nene rating above 33, with the first third at 35-6, and combined with the adrenaline of bumps keeping high power and efficient rowing (which has come on over the past week a huge amount) shouldn't be too much of a problem.
Which can be compared to Clare Hall M1 who plan to do bumps at rate 27 or so...
In other news, how much have Caius stacked their first boat? I've been hearing rumours and all kinds of gossip about what they could do and the people they have available, have they changed anything yet?
