That sounds like a nice 1000, quixoticgeek! I will at least ride part of it (depending on my other plans). In terms of timing, isn't 300-400-300 a better sequence? For the faster riders, that would allow for a more natural schedule: day 1, start at 8:00, complete 300k around 22:00. Then day 2, start at 4:00, complete 400k around midnight. On day 3, you can do the remaining 300 at a leisurely pace.
