I am mightily impressed by your consistency and general endurance. That is a bit over twice the best year I have put up, and over 6 times the puny 120,000 I had this year (second lowest of the last 7). 700,000 seems like it should be doable - just 2,000 per day, but it would demand some real stick-to-it-iveness. Perhaps I should start today, given that it is a new rowing year.
