Pumps are nothing new it’s just that like mtb lights, because batteries are now much lighter they’re getting more practical.
Anyway, decent races. I’d say that the Cambridge women lost due to coxing. Not to say that she really screwed it up but as a long time Tideway rower, the best coxes would have read the water better and got them out of the worst of it.
And that’s the interesting thing, we often raced boat race crews in the run up to the race and beat them, often not from being faster but through dealing with the river better (which is exactly why they came to race us )
